Copyright 2012 Texas Instruments Incorporated PRODUCT PREVIEW 1 Features TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 1.1 KeyStone Architecture TI's KeyStone Multicore Architecture provides a high performance structure for integrating RISC and DSP cores with application specific coprocessors and I/O. KeyStone is the first of its kind that provides adequate internal bandwidth for nonblocking access to all processing cores, peripherals, coprocessors, and I/O. This is achieved with four main hardware elements: Multicore Navigator, TeraNet, Multicore Shared Memory Controller, and HyperLink. PRODUCT PREVIEW Multicore Navigator is an innovative packet-based manager that controls 8192 queues. When tasks are allocated to the queues, Multicore Navigator provides hardware-accelerated dispatch that directs tasks to the appropriate available hardware. The packet-based system on a chip (SoC) uses the two Tbps capacity of the TeraNet switched central resource to move packets. The Multicore Shared Memory Controller enables processing cores to access shared memory directly without drawing from TeraNet's capacity, so packet movement cannot be blocked by memory access. HyperLink provides a 40-Gbaud chip-level interconnect that allows SoCs to work in tandem. Its low-protocol overhead and high throughput make HyperLink an ideal interface for chip-to-chip interconnections. Working with Multicore Navigator, HyperLink dispatches tasks to tandem devices transparently and executes tasks as if they are running on local resources. 1.2 Device Description The TMS320C6654 DSP is a highest-performance fixed/floating-point DSP that is based on TI's KeyStone multicore architecture. Incorporating the new and innovative C66x DSP core, this device can run at a core speed of up to 850 MHz. For developers of a broad range of applications, such as mission critical, medical imaging, test and automation, and other applications requiring high performance, TI's TMS320C6654 DSP offers up to 850 MHz cumulative DSP and enables a platform that is power-efficient and easy to use. In addition, it is fully backward compatible with all existing C6000 family of fixed and floating point DSPs. TI's KeyStone architecture provides a programmable platform integrating various subsystems (C66x cores, memory subsystem, peripherals, and accelerators) and uses several innovative components and techniques to maximize intra-device and inter-device communication that allows the various DSP resources to operate efficiently and seamlessly. Central to this architecture are key components such as Multicore Navigator that allows for efficient data management between the various device components. The TeraNet is a non-blocking switch fabric enabling fast and contention-free internal data movement. The multicore shared memory controller allows access to shared and external memory directly without drawing from switch fabric capacity. For fixed-point use, the C66x core has 4x the multiply accumulate (MAC) capability of C64x+ cores. In addition, the C66x core integrates floating point capability and the per core raw computational performance is an industry-leading 32 MACS/cycle and 16 flops/cycle. It can execute 8 single precision floating point MAC operations per cycle and can perform double- and mixed-precision operations and is IEEE754 compliant. The C66x core incorporates 90 new instructions (compared to the C64x+ core) targeted for floating point and vector math oriented processing. These enhancements yield sizeable performance improvements in popular DSP kernels used in signal processing, mathematical, and image acquisition functions. The C66x core is backwards code compatible with TI's previous generation C6000 fixed and floating point DSP cores, ensuring software portability and shortened software development cycles for applications migrating to faster hardware. The C6654 DSP integrates a large amount of on-chip memory. In addition to 32KB of L1 program and data cache, there is 1024KB of dedicated memory per core that can be configured as mapped RAM or cache. All L2 memories incorporate error detection and error correction.

Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions Device Overview 17 TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 2.2 DSP Core Description The C66x Digital Signal Processor (DSP) extends the performance of the C64x+ and C674x DSPs through enhancements and new features. Many of the new features target increased performance for vector processing. The C64x+ and C674x DSPs support 2-way SIMD operations for 16-bit data and 4-way SIMD operations for 8-bit data. On the C66x DSP, the vector processing capability is improved by extending the width of the SIMD instructions. C66x DSPs can execute instructions that operate on 128-bit vectors. For example the QMPY32 instruction is able to perform the element-to-element multiplication between two vectors of four 32-bit data each. The C66x DSP also supports SIMD for floating-point operations. Improved vector processing capability (each instruction can process multiple data in parallel) combined with the natural instruction level parallelism of C6000 architecture (e.g execution of up to 8 instructions per cycle) results in a very high level of parallelism that can be exploited by DSP programmers through the use of TI's optimized C/C++ compiler. PRODUCT PREVIEW The C66x DSP consists of eight functional units, two register files, and two data paths as shown in Figure 2-1. The two general-purpose register files (A and B) each contain 32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, and 64-bit data. Multiplies also support 128-bit data. 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 MSBs in the next upper register (which is always an odd-numbered register). 128-bit data values are stored in register quadruplets, with the 32 LSBs of data placed in a register that is a multiple of 4 and the remaining 96 MSBs in the next 3 upper registers. The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from memory to the register file and store results from the register file into memory. Each C66x .M unit can perform one of the following fixed-point operations each clock cycle: four 32 x 32 bit multiplies, sixteen 16 x 16 bit multiplies, four 16 x 32 bit multiplies, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities. There is also support for Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require complex multiplication. Each C66x .M unit can perform one 16 x 16 bit complex multiply with or without rounding capabilities, two 16 x 16 bit complex multiplies with rounding capability, and a 32 x 32 bit complex multiply with rounding capability. The C66x can also perform two 16 x 16 bit and one 32 x 32 bit complex multiply instructions that multiply a complex number with a complex conjugate of another number with rounding capability. Communication signal processing also requires an extensive use of matrix operations. Each C66x .M unit is capable of multiplying a [1 x 2] complex vector by a [2 x 2] complex matrix per cycle with or without rounding capability. A version also exists allowing multiplication of the conjugate of a [1 x 2] vector with a [2 x 2] complex matrix. Each C66x .M unit also includes IEEE floating-point multiplication operations from the C674x DSP, which includes one single-precision multiply each cycle and one double-precision multiply every 4 cycles. There is also a mixed-precision multiply that allows multiplication of a single-precision value by a double-precision value and an operation allowing multiplication of two single-precision numbers resulting in a double-precision number. The C66x DSP improves the performance over the C674x double-precision multiplies by adding a instruction allowing one double-precision multiply per cycle and also reduces the number of delay slots from 10 down to 4. Each C66x .M unit can also perform one the following floating-point operations each clock cycle: one, two, or four single-precision multiplies or a complex single-precision multiply. The .L and .S units can now support up to 64-bit operands. This allows for new versions of many of the arithmetic, logical, and data packing instructions to allow for more parallel operations per cycle. Additional instructions were added yielding performance enhancements of the floating point addition and subtraction instructions, including the ability to perform one double precision addition or subtraction per cycle. Conversion to/from integer and single-precision values can now be done on both .L and .S units on the C66x. Also, by taking advantage of the larger 18 Device Overview Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor www.ti.com SPRS841--March 2012 The MFENCE instruction is a new instruction introduced on the C66x DSP. This instruction will create a DSP stall until the completion of all the DSP-triggered memory transactions, including: * Cache line fills * Writes from L1D to L2 or from the CorePac to MSMC and/or other system endpoints * Victim write backs * Block or global coherence operations * Cache mode changes * Outstanding XMC prefetch requests This is useful as a simple mechanism for programs to wait for these requests to reach their endpoint. It also provides ordering guarantees for writes arriving at a single endpoint via multiple paths, multiprocessor algorithms that depend on ordering, and manual coherence operations.

The .L unit also has additional instructions for logical AND and OR instructions, as well as, 90 degree or 270 degree rotation of complex numbers (up to two per cycle). Instructions have also been added that allow for the computing the conjugate of a complex number.

More than 32MB allowed by NAND flash The boot sequence is a process by which the DSP's internal memory is loaded with program and data sections. The DSP's internal registers are programmed with predetermined values. The boot sequence is started automatically after each power-on reset, warm reset, and system reset. A local reset to an individual C66x CorePac should not affect the state of the hardware boot controller on the device. For more details on the initiators of the resets, see section 7.4 ``Reset Controller'' on page 119. The bootloader uses a section of the L2 SRAM (start address 0x0087 2DC0 and end address 0x0087 FFFF) during initial booting of the device. For more details on the type of configurations stored in this reserved L2 section see the Bootloader for the C66x DSP User Guide in ``Related Documentation from Texas Instruments'' on page 64. The C6654 supports several boot processes that begins execution at the ROM base address, which contains the bootloader code necessary to support various device boot modes. The boot processes are software-driven and use the BOOTMODE[12:0] device configuration inputs to determine the software configuration that must be completed. For more details on Boot Sequence see the Bootloader for the C66x DSP User Guide in ``Related Documentation from Texas Instruments'' on page 64. 2.5 Boot Modes Supported and PLL Settings The device supports several boot processes, which leverage the internal boot ROM. Most boot processes are software driven, using the BOOTMODE[2:0] device configuration inputs to determine the software configuration that must be completed. From a hardware perspective, there are two possible boot modes: * Public ROM Boot - C66x CorePac0 is released from reset and begins executing from the L3 ROM base address. After performing the boot process (e.g., from I2C ROM, Ethernet, or RapidIO), C66x CorePac0 then begins execution from the provided boot entry point. For C6657 only, the other C66x CorePac is released from reset and begins executing an IDLE from the L3 ROM. It is then released from IDLE based on interrupts generated by C66x CorePac0. See the Bootloader for the C66x DSP User Guide in ``Related Documentation from Texas Instruments'' on page 64 for more details. * Secure ROM Boot - On secure devices, the C66x CorePac0 is released from reset and begin executing from secure ROM. Software in the secure ROM will free up internal RAM pages, after which C66x CorePac0 initiates the boot process. The C66x CorePac0 performs any authentication and decryption required on the bootloaded image prior to beginning execution.

www.ti.com 2.9 Development and Support 2.9.1 Development Support In case the customer would like to develop their own features and software on the C6654 device, TI offers an extensive line of development tools for the TMS320C6000TM DSP platform, including tools to evaluate the performance of the processors, generate code, develop algorithm implementations, and fully integrate and debug software and hardware modules. The tool's support documentation is electronically available within the Code Composer StudioTM Integrated Development Environment (IDE). PRODUCT PREVIEW The following products support development of C6000TM DSP-based applications: * Software Development Tools: - Code Composer StudioTM Integrated Development Environment (IDE), including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools. - Scalable, Real-Time Foundation Software (DSP/BIOSTM), which provides the basic run-time target software needed to support any DSP application. * Hardware Development Tools: - Extended Development System (XDSTM) Emulator (supports C6000TM DSP multiprocessor system debug) - EVM (Evaluation Module) 2.9.2 Device Support 2.9.2.1 Device and Development-Support Tool Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g., TMX320CMH). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS). Device development evolutionary flow: * TMX: Experimental device that is not necessarily representative of the final device's electrical specifications * TMP: Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification * TMS: Fully qualified production device Support tool development evolutionary flow: * TMDX: Development-support product that has not yet completed Texas Instruments internal qualification testing. * TMDS: Fully qualified development-support product TMX and TMP devices and TMDX development-support tools are shipped with the following disclaimer: "Developmental product is intended for internal evaluation purposes." TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. 62 Device Overview Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com TI device nomenclature also includes a suffix with the device family name.

The status of the peripherals (enabled/disabled) is determined after device power-on reset. Table 3-1 describes the device configuration pins. The logic level is latched at power-on reset to determine the device configuration. The logic level on the device configuration pins can be set by using external pullup/pulldown resistors or by using some control device (e.g., FPGA/CPLD) to intelligently drive these pins. When using a control device, care should be taken to ensure there is no contention on the lines when the device is out of reset. The device configuration pins are sampled during power-on reset and are driven after the reset is removed. To avoid contention, the control device must stop driving the device configuration pins of the DSP. And when driving by a control device, the control device must be fully powered and out of reset itself and driving the pins before the DSP can be taken out of reset. Also, please note that most of the device configuration pins are shared with other function pins (LENDIAN/GPIO[0], BOOTMODE[12:0]/GPIO[13:1], PCIESSMODE[1:0]/GPIO[15:14] and PCIESSEN/TIMI0), some time must be given following the rising edge of reset in order to drive these device configuration input pins before they assume an output state (those GPIO pins should not become outputs during boot). Another caution that needs to be noted is that systems using TIMI0 (pin shared with PCIESSEN) as a clock input must assure that the clock itself is disabled from the input until after reset is released and a control device is no longer driving that input. Note--If a configuration pin must be routed out from the device and it is not driven (Hi-Z state), the internal pullup/pulldown (IPU/IPD) resistor should not be relied upon. TI recommends the use of an external pullup/pulldown resistor. For more detailed information on pullup/pulldown resistors and situations in which external pullup/pulldown resistors are required, see Section 3.4 ``Pullup/Pulldown Resistors'' on page 86.

By default, the PCIe is held in reset and clock-gated. The memory in this module is also in a low-leakage sleep mode. Software is required to turn this memory on. The software enables the module (turns on clocks and de-asserts reset) before this module can be used. If one of the above modules is used in the selected ROM boot mode, the ROM code will automatically enable the module. All other modules come up enabled by default and there is no special software sequence to enable. For more detailed information on the PSC usage, see the Power Sleep Controller (PSC) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64.

See the Silicon Errata for details. 3.3.4 Kicker Mechanism (KICK0 and KICK1) Register The Bootcfg module contains a kicker mechanism to prevent any spurious writes from changing any of the Bootcfg MMR values. When the kicker is locked (which it is initially after power on reset) none of the Bootcfg MMRs are writable (they are only readable). On the C6654, the exception to this are the IPC registers such as IPCGRx and IPCARx. These registers are not protected by the kicker mechanism. This mechanism requires two MMR writes to the KICK0 and KICK1 registers with exact data values before the kicker lock mechanism is un-locked. See Table 3-2 ``Device State Control Registers'' on page 66 for the address location. Once released then all the Bootcfg MMRs having write permissions are writable (the read only MMRs are still read only). The first KICK0 data is 0x83e70b13. The second KICK1 data is 0x95a4f1e0. Writing any other data value to either of these kick MMRs will lock the kicker mechanism and block any writes to Bootcfg MMRs. To ensure protection to all Bootcfg MMRs, software must always re-lock the kicker mechanism after completing the MMR writes.

The C6654 has only IPCGR0. This register can be used by external hosts to generate interrupts to the CorePac. A write of 1 to the IPCG field of the IPCGRx register will generate an interrupt pulse to the CorePac. This register also provides a Source ID facility by which up to 28 different sources of interrupts can be identified. Allocation of source bits to source processor and meaning is entirely based on software convention. The register field descriptions are given in the following tables. Virtually anything can be a source for these registers as this is completely controlled by software. Any master that has access to BOOTCFG module space can write to these registers.

This may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup/pulldown resistors. An external pullup/pulldown resistor needs to be used in the following situations: * Device Configuration Pins: If the pin is both routed out and are not driven (in Hi-Z state), an external pullup/pulldown resistor must be used, even if the IPU/IPD matches the desired value/state. * Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown resistor to pull the signal to the opposite rail. PRODUCT PREVIEW For the device configuration pins (listed in Table 3-1), if they are both routed out and are not driven (in Hi-Z state), it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing external connectivity can help ensure that valid logic levels are latched on these device configuration pins. In addition, applying external pullup/pulldown resistors on the device configuration pins adds convenience to the user in debugging and flexibility in switching operating modes. Tips for choosing an external pullup/pulldown resistor: * Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown resistors. * Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which, by definition, have margin to the VIL and VIH levels. * Select a pullup/pulldown resistor with the largest possible value that can still ensure that the net will reach the target pulled value when maximum current from all devices on the net is flowing through the resistor. The current to be considered includes leakage current plus, any other internal and external pullup/pulldown resistors on the net. * For bidirectional nets, there is an additional consideration that sets a lower limit on the resistance value of the external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to the opposite logic level (including margin). * Remember to include tolerances when selecting the resistor value. * For pullup resistors, also remember to include tolerances on the DVDD rail. For most systems: * A 1-k resistor can be used to oppose the IPU/IPD while meeting the above criteria. Users should confirm this resistor value is correct for their specific application. * A 20-k resistor can be used to compliment the IPU/IPD on the device configuration pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific application. For more detailed information on input current (II), and the low-level/high-level input voltages (VIL and VIH) for the TMS320C6654 device, see Section 6.3 ``Electrical Characteristics'' on page 105. To determine which pins on the device include internal pullup/pulldown resistors, see Table 2-17 ``Terminal Functions -- Signals and Control by Function'' on page 38. 86 Device Configuration Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor www.ti.com SPRS841--March 2012 4 System Interconnect On the TMS320C6654 device, the C66x CorePac, the EDMA3 transfer controller, and the system peripherals are interconnected through the TeraNet, which is a non-blocking switch fabric enabling fast and contention-free internal data movement. The TeraNet allows for low-latency, concurrent data transfers between master peripherals and slave peripherals. The TeraNet also allows for seamless arbitration between the system masters when accessing system slaves. 4.1 Internal Buses and Switch Fabrics The C66x CorePac, the EDMA3 traffic controller, and the various system peripherals can be classified into two categories: masters and slaves. Masters are capable of initiating read and write transfers in the system and do not rely on the EDMA3 for their data transfers. Slaves, on the other hand, rely on the masters to perform transfers to and from them. Examples of masters include the EDMA3 traffic controller and PCI Express. Examples of slaves include 2 the SPI, UART, and I C. The masters and slaves in the device are communicating through the TeraNet (switch fabric). The device contains two switch fabrics. The data switch fabric (data TeraNet) and the configuration switch fabric (configuration TeraNet). The data TeraNet, is a high-throughput interconnect mainly used to move data across the system. The data TeraNet connects masters to slaves via data buses. The configuration TeraNet, is mainly used to access peripheral registers. The configuration TeraNet connects masters to slaves via configuration buses. Note that the data TeraNet also connects to the configuration TeraNet. For more details see 4.2 ``Switch Fabric Connections Matrix'' on page 88. Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions System Interconnect 87 PRODUCT PREVIEW Two types of buses exist in the device: data buses and configuration buses. Some peripherals have both a data bus and a configuration bus interface, while others have only one type of interface. Further, the bus interface width and speed varies from peripheral to peripheral. Configuration buses are mainly used to access the register space of a peripheral and the data buses are used mainly for data transfers.

User programmable priority registers allow software configuration of the data traffic through the TeraNet. Note that a lower number means higher priority - PRI = 000b = urgent, PRI = 111b = low. Most master ports provide their priority directly and do not need a default priority setting. Examples include the CorePacs, whose priorities are set through software in the UMC control registers. All the packet-DMA-based peripherals also have internal registers to define the priority level of their initiated transactions. Some masters do not have apriority allocation register of their own. For these masters, a priority allocation register is provided for them and described in the sections below. For all other modules, see the respective User Guides in "Related Documentation from Texas Instruments" on page 64 for programmable priority registers.

For example, address location 0x10800000 is the global base address for C66x CorePac Core 0's L2 memory. C66x CorePac Core 0 can access this location by either using 0x10800000 or 0x00800000. Any other master on the device must use 0x10800000 only. Conversely, 0x00800000 can by used by any of the cores as their own L2 base addresses. For C66x CorePac Core 0, address 0x00800000 is equivalent to 0x10800000. Local addresses should be used only for shared code or data, allowing a single image to be included in memory. Any code/data targeted to a specific core, or a memory region allocated during run-time by a particular core should always use the global address only.

The ROM contains software used to boot the device. There is no requirement to block accesses from this portion to the ROM. PRODUCT PREVIEW 5.2 Memory Protection Memory protection allows an operating system to define who or what is authorized to access L1D, L1P, and L2 memory. To accomplish this, the L1D, L1P, and L2 memories are divided into pages. There are 16 pages of L1P (2KB each), 16 pages of L1D (2KB each), and 32 pages of L2 (16KB each). The L1D, L1P, and L2 memory controllers in the C66x CorePac are equipped with a set of registers that specify the permissions for each memory page. Each page may be assigned with fully orthogonal user and supervisor read, write, and execute permissions. In addition, a page may be marked as either (or both) locally accessible or globally accessible. A local access is a direct DSP access to L1D, L1P, and L2, while a global access is initiated by a DMA (either IDMA or the EDMA3) or by other system masters. Note that EDMA or IDMA transfers programmed by the DSP count as global accesses. On a secure device, pages can be restricted to secure access only (default) or opened up for public, non-secure access. The DSP and each of the system masters on the device are all assigned a privilege ID. It is possible to specify whether memory pages are locally or globally accessible. The AIDx and LOCAL bits of the memory protection page attribute registers specify the memory page protection scheme, see Table 5-1. Table 5-1 Available Memory Page Protection Schemes AIDx Bit Local Bit 0 0 Description No access to memory page is permitted. 0 1 Only direct access by DSP is permitted. 1 0 Only accesses by system masters and IDMA are permitted (includes EDMA and IDMA accesses initiated by the DSP). 1 1 All accesses permitted. End of Table 5-1 Faults are handled by software in an interrupt (or an exception, programmable within the C66x CorePac interrupt controller) service routine. A DSP or DMA access to a page without the proper permissions will: * Block the access -- reads return 0, writes are ignored * Capture the initiator in a status register -- ID, address, and access type are stored * Signal event to DSP interrupt controller The software is responsible for taking corrective action to respond to the event and resetting the error status in the memory controller.

These operations are: * DSP-initiated transfers * User-programmed cache coherency operations * IDMA-initiated transfers The priority level for operations initiated outside the C66x CorePac by system peripherals is declared through the Priority Allocation Register (PRI_ALLOC), see section 4.4 ``Bus Priorities'' on page 94 for more details. System peripherals with no fields in the PRI_ALLOC have their own registers to program their priorities. More information on the bandwidth management features of the C66x CorePac can be found in the C66x CorePac User Guide in ``Related Documentation from Texas Instruments'' on page 64. 5.4 Power-Down Control The C66x CorePac supports the ability to power down various parts of the C66x CorePac. The power down controller (PDC) of the C66x CorePac can be used to power down L1P, the cache control hardware, the DSP, and the entire C66x CorePac. These power-down features can be used to design systems for lower overall system power requirements. Note--The C6654 does not support power-down modes for the L2 memory at this time. More information on the power-down features of the C66x CorePac can be found in the TMS320C66x CorePac Reference Guide in ``Related Documentation from Texas Instruments'' on page 64.

The various power supply rails and their primary function is listed in Table 7-1. TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 7.2.1 Power-Supply Sequencing This section defines the requirements for a power up sequencing from a power-on reset condition. There are two acceptable power sequences for the device. The first sequence stipulates the core voltages starting before the IO voltages as shown below. 1. CVDD 2. CVDD1, VDDT1-2 3. DVDD18, AVDDA1, AVDDA2 4. DVDD15, VDDR1-4 PRODUCT PREVIEW The second sequence provides compatibility with other TI processors with the IO voltage starting before the core voltages as shown below. 1. DVDD18, AVDDA1, AVDDA2 2. CVDD 3. CVDD1, VDDT1-2 4. DVDD15, VDDR1-4 The clock input buffers for CORECLK, DDRCLK, SRIOSGMIICLK, and PCIECLK use only CVDD as a supply voltage. These clock inputs are not failsafe and must be held in a high-impedance state until CVDD is at a valid voltage level. Driving these clock inputs high before CVDD is valid could cause damage to the device. Once CVDD is valid it is acceptable that the P and N legs of these CLKs may be held in a static state (either high and low or low and high) until a valid clock frequency is needed at that input. To avoid internal oscillation the clock inputs should be removed from the high impedance state shortly after CVDD is present. If a clock input is not used it must be held in a static state. To accomplish this the N leg should be pulled to ground through a 1K ohm resistor. The P leg should be tied to CVDD to ensure it won't have any voltage present until CVDD is active. Connections to the IO cells powered by DVDD18 and DVDD15 are not failsafe and should not be driven high before these voltages are active. Driving these IO cells high before DVDD18 or DVDD15 are valid could cause damage to the device. The device initialization is broken into two phases. The first phase consists of the time period from the activation of the first power supply until the point in which all supplies are active and at a valid voltage level. Either of the sequencing scenarios described above can be implemented during this phase. The figures below show both the core-before-IO voltage sequence and the IO-before-core voltage sequence. POR must be held low for the entire power stabilization phase. This is followed by the device initialization phase. The rising edge of POR followed by the rising edge of RESETFULL will trigger the end of the initialization phase but both must be inactive for the initialization to complete. POR must always go inactive before RESETFULL goes inactive as described below. SYSCLK1 in the following section refers to the clock that is used by the CorePac, see Figure 7-7 for more details. 7.2.1.1 Core-Before-IO Power Sequencing Figure 7-1 shows the power sequencing and reset control of TMS320C6654 for device initialization. POR may be removed after the power has been stable for the required 100 sec. RESETFULL must be held low for a period after the rising edge of POR but may be held low for longer periods if necessary. The configuration bits shared with the GPIO pins will be latched on the rising edge of RESETFULL and must meet the setup and hold times specified. 108 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com SYSCLK1 must always be active before POR can be removed.

The device should not be held in a reset for times exceeding one hour and should not be held in reset for more the 5% of the time during which power is applied. Exceeding these limits will cause a gradual reduction in the reliability of the part. This can be avoided by allowing the DSP to boot and then configuring it to enter a hibernation state soon after power is applied. This will satisfy the reset requirement while limiting the power consumption of the device. 7.2.1.4 Clocking During Power Sequencing Some of the clock inputs are required to be present for the device to initialize correctly, but behavior of many of the clocks is contingent on the state of the boot configuration pins. Table 7-4 describes the clock sequencing and the conditions that affect the clock operation. Note that all clock drivers should be in a high-impedance state until CVDD is at a valid level and that all clock inputs either be active or in a static state with one leg pulled low and the other connected to CVDD. 112 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com Table 7-4 Clock Sequencing Clock Condition DDRCLK None Must be present 16 sec before POR transitions high. CORECLK None CORECLK used to clock the core PLL. It must be present 16 sec before POR transitions high. SRIOSGMIICLK PCIECLK Sequencing The SGMII port will be used. SRIOSGMIICLK must be present 16 sec before POR transitions high. SGMII will not be used. SRIOSGMIICLK is not used and should be tied to a static state. PCIE will be used as a boot device. PCIECLK must be present 16 sec before POR transitions high. PCIE will be used after boot. PCIECLK is used as a source to the PCIE SERDES PLL. It must be present before the PCIE is removed from reset and programmed. PCIE will not be used. PCIECLK is not used and should be tied to a static state. 7.2.2 Power-Down Sequence The power down sequence is the exact reverse of the power-up sequence described above. The goal is to prevent a large amount of static current and to prevent overstress of the device. A power-good circuit that monitors all the supplies for the device should be used in all designs. If a catastrophic power supply failure occurs on any voltage rail, POR should transition to low to prevent over-current conditions that could possibly impact device reliability. A system power monitoring solution is needed to shut down power to the board if a power supply fails. Long-term exposure to an environment in which one of the power supply voltages is no longer present will affect the reliability of the device. Holding the device in reset is not an acceptable solution because prolonged periods of time with an active reset can also affect long term reliability. 7.2.3 Power Supply Decoupling and Bulk Capacitors In order to properly decouple the supply planes on the PCB from system noise, decoupling and bulk capacitors are required. Bulk capacitors are used to minimize the effects of low frequency current transients and decoupling or bypass capacitors are used to minimize higher frequency noise. For recommendations on selection of Power Supply Decoupling and Bulk capacitors see the Hardware Design Guide for KeyStone Devices in ``Related Documentation from Texas Instruments'' on page 64. 7.2.4 SmartReflex Increasing the device complexity increases its power consumption and with the smaller transistor structures responsible for higher achievable clock rates and increased performance, comes an inevitable penalty, increasing the leakage currents. Leakage currents are present in any active circuit, independently of clock rates and usage scenarios. This static power consumption is mainly determined by transistor type and process technology. Higher clock rates also increase dynamic power, the power used when transistors switch. The dynamic power depends mainly on a specific usage scenario, clock rates, and I/O activity. Texas Instruments' SmartReflex technology is used to decrease both static and dynamic power consumption while maintaining the device performance. SmartReflex in the TMS320C6654 device is a feature that allows the core voltage to be optimized based on the process corner of the device. This requires a voltage regulator for each TMS320C6654 device. To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is required to be implemented whenever the TMS320C6654 device is used. The voltage selection is done using 4 VCNTL pins which are used to select the output voltage of the core voltage regulator.

The PSC provides the user with an interface to control several important power and clock operations. For information on the Power Sleep Controller, see the Power Sleep Controller (PSC) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. 7.3.1 Power Domains The device has several power domains that can be turned on for operation or off to minimize power dissipation.

The device has several types of resets: * Power-on reset * Hard reset * Soft reset * CPU local reset Table 7-9 explains further the types of reset, the reset initiator, and the effects of each reset on the device. For more information on the effects of each reset on the PLL controllers and their clocks, see Section ``Reset Electrical Data / Timing'' on page 123 Table 7-9 Reset Type Reset Types Initiator POR (Power On Reset) POR pin active low RESETFULL pin active low Hard reset RESET pin active low Emulation PLLCTL register (RSCTRL) Watchdog timers Soft reset RESET pin active low PLLCTL register (RSCTRL) Watchdog timers C66x CorePac local reset Software (through LPSC MMR) Watchdog timers LRESET pin Effect on Device When Reset Occurs RESETSTAT Pin Status Toggles RESETSTAT pin Total reset of the chip. Everything on the device is reset to its default state in response to this. Activates the POR signal on chip, which is used to reset test/emu logic. Boot configurations are latched. ROM boot process is initiated. Resets everything except for test/emu logic and reset isolation modules. Emulator and reset Isolation modules stay alive during this reset. This reset is also different from POR in that the PLLCTL assumes power and clocks are stable when device reset is asserted. Boot configurations are not latched. ROM boot process is initiated. Toggles RESETSTAT pin Software can program these initiators to be hard or soft. Hard reset is the default, but can be programmed to be soft reset. Soft reset will behave like hard reset except that EMIF16 MMRs, DDR3 EMIF MMRs, sticky bits in PCIe MMRs, and external memory contents are retained. Boot configurations are not latched. ROM boot process is initiated. Toggles RESETSTAT pin MMR bit in LPSC controls C66x CorePac local reset.

Power-on reset is initiated by the following 1. POR pin 2. RESETFULL pin PRODUCT PREVIEW During power-up, the POR pin must be asserted (driven low) until the power supplies have reached their normal operating conditions. A RESETFULL pin is also provided to allow the on-board host to reset the entire device including the reset isolated logic. The assumption is that, device is already powered up and hence unlike POR, RESETFULL pin will be driven by the on-board host control other than the power good circuitry. For power-on reset, the Main PLL Controller comes up in bypass mode and the PLL is not enabled. Other resets do not affect the state of the PLL or the dividers in the PLL controller. The following sequence must be followed during a power-on reset: 1. Wait for all power supplies to reach normal operating conditions while keeping the POR pin asserted (driven low). While POR is asserted, all pins except RESETSTAT will be set to high-impedance. After the POR pin is de-asserted (driven high), all Z group pins, low group pins, and high group pins are set to their reset state and will remain at their reset state until otherwise configured by their respective peripheral. All peripherals that are power managed, are disabled after a Power-on Reset and must be enabled through the Device State Control registers (for more details, see Section Table 3-2 ``Device State Control Registers'' on page 66). 2. Clocks are reset, and they are propagated throughout the chip to reset any logic that was using reset synchronously. All logic is now reset and RESETSTAT will be driven low indicating that the device is in reset. 3. POR must be held active until all supplies on the board are stable then for at least an additional time for the Chip level PLLs to lock. 4. The POR pin can now be de-asserted. Reset sampled pin values are latched at this point. The Chip level PLLs is taken out of reset and begins its locking sequence, and all power-on device initialization also begins. 5. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high). By this time, DDR3 PLL has already completed its locking sequence and is outputting a valid clock. The system clocks of both PLL controllers are allowed to finish their current cycles and then paused for 10 cycles of their respective system reference clocks. After the pause, the system clocks are restarted at their default divide by settings. 6. The device is now out of reset and device execution begins as dictated by the selected boot mode. Note--To most of the device, reset is de-asserted only when the POR and RESET pins are both de-asserted (driven high). Therefore, in the sequence described above, if the RESET pin is held low past the low period of the POR pin, most of the device will remain in reset. The RESET pin should not be tied together with the POR pin. 120 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor www.ti.com SPRS841--March 2012 7.4.2 Hard Reset A hard reset will reset everything on the device except the PLLs, test, emulation logic, and reset isolation modules. POR should also remain de-asserted during this time. Hard reset is initiated by the following * RESET pin * RSCTRL register in PLLCTL * Watchdog timer * Emulation The following sequence must be followed during a Hard reset: 1. The RESET pin is pulled active low for a minimum of 24 input clock cycles. During this time the RESET signal is able to propagate to all modules (except those specifically mentioned above). All I/O are Hi-Z for modules affected by RESET, to prevent off-chip contention during the warm reset. 2. Once all logic is reset, RESETSTAT is driven active to denote that the device is in reset. 3. The RESET pin can now be released. A minimal device initialization begins to occur. Note that configuration pins are not re-latched and clocking is unaffected within the device. 4. After device initialization is complete, the RESETSTAT pin is de-asserted (driven high). Note--The POR pin should be held inactive (high) throughout the warm reset sequence. Otherwise, if POR is activated (brought low), the minimum POR pulse width must be met. The RESET pin should not be tied together with the POR pin. Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions Peripheral Information and Electrical Specifications 121 PRODUCT PREVIEW All the above initiators by default are configured to act as hard reset. Except emulation, all the other 3 initiators can be configured as Soft resets in the RSCFG register in PLLCTL. TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 7.4.3 Soft Reset A soft reset will behave like a hard reset except that the PCIe MMR sticky bits and DDR3 EMIF MMRs contents are retained. POR should also remain de-asserted during this time. Soft reset is initiated by the following * RESET pin * RSCTRL register in PLLCTL * Watchdog timer All the above initiators by default are configured to act as hard reset. Except emulation, all the other 3 initiators can be configured as soft resets in the RSCFG register in PLLCTL. PRODUCT PREVIEW In the case of a soft reset, the clock logic or the power control logic of the peripherals are not affected, and, therefore, the enabled/disabled state of the peripherals is not affected. On a soft reset, the DDR3 memory controller registers are not reset. In addition, the DDR3 SDRAM memory content is retained if the user places the DDR3 SDRAM in self-refresh mode before invoking the soft reset. During a soft reset, the following happens: 1. The RESETSTAT pin goes low to indicate an internal reset is being generated. The reset is allowed to propagate through the system. Internal system clocks are not affected. PLLs also remain locked. 2. After device initialization is complete, the RESETSTAT pin is deasserted (driven high). In addition, the PLL controllers pause their system clocks for about 8 cycles. At this point: The state of the peripherals before the soft reset is not changed. The I/O pins are controlled as dictated by the DEVSTAT register. The DDR3 MMRs and PCIe MMR sticky bits retain their previous values. Only the DDR3 Memory Controller and PCIe state machines are reset by the soft reset. The PLL controllers are operating in the mode prior to soft reset. System clocks are unaffected. The boot sequence is started after the system clocks are restarted. Since the configuration pins are not latched with a System Reset, the previous values, as shown in the DEVSTAT register, are used to select the boot mode. 122 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 7.4.4 Local Reset Local reset is initiated by the following (for more details see the Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64: * LRESET pin * Watchdog timer should cause one of the below based on the setting of the CORESEL[2:0] and RSTCFG register in the PLL controller.

The complete 13-bit value is latched when the GO operation is initiated in the PLL controller. Only PLLDIV2, PLLDIV5, and PLLDIV8 are programmable on the C6654 device. See the Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64 for more details on how to program the PLL controller. Main PLL power is supplied externally via the Main PLL power-supply pin (AVDDA1). An external EMI filter circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices in ``Related Documentation from Texas Instruments'' on page 64 for detailed recommendations. For the best performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or components other than those shown. For reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external components (C1, C2, and the EMI Filter). The minimum SYSCLK rise and fall times should also be observed. For the input clock timing requirements, see Section 7.5.5 ``Main PLL Controller/PCIe Clock Input Electrical Data/Timing''. CAUTION--The PLL controller module as described in the see the Phase Locked Loop (PLL) Controller for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64 includes a superset of features, some of which are not supported on the TMS320C6654 device. The following sections describe the registers that are supported; it should be assumed that any registers not included in these sections is not supported by the device. Furthermore, only the bits within the registers described here are supported. Avoid writing to any reserved memory location or changing the value of reserved bits. 7.5.1 Main PLL Controller Device-Specific Information 7.5.1.1 Internal Clocks and Maximum Operating Frequencies The Main PLL, used to drive the CorePacs, the switch fabric, and a majority of the peripheral clocks (all but the DDR3) requires a PLL controller to manage the various clock divisions, gating, and synchronization. The Main PLL's PLL controller has several SYSCLK outputs that are listed below, along with the clock description. Each SYSCLK has a corresponding divider that divides down the output clock of the PLL. Note that dividers are not programmable unless explicitly mentioned in the description below. * SYSCLK1: Full-rate clock for the CorePac. * SYSCLK2: 1/x-rate clock for CorePac emulation. Default rate for this will be 1/3. This is programmable from /1 to /32, where this clock does not violate the max of 350 MHz. The SYSCLK2 can be turned off by software. * SYSCLK3: 1/2-rate clock used to clock the MSMC and DDR EMIF. * SYSCLK4: 1/3-rate clock for the switch fabrics and fast peripherals. The Debug_SS and ETBs will use this as well. * SYSCLK5: 1/y-rate clock for system trace module only. Default rate for this will be 1/5. It is configurable and the max configurable clock is 210 MHz and min configuration clock is 32 MHz. The SYSCLK5 can be turned off by software. * SYSCLK6: 1/64-rate clock. 1/64 rate clock (emif_ptv) used to clock the PVT compensated buffers for DDR3 EMIF.

The PLL controller also controls reset propagation through the chip, clock alignment, and test points. The PLL controller monitors the PLL status and provides an output signal indicating when the PLL is locked. TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 * * * * www.ti.com SYSCLK7: 1/6-rate clock for slow peripherals and sources the SYSCLKOUT output pin. SYSCLK8: 1/z-rate clock. This clock is used as slow_sysclk in the system. Default for this will be 1/64. This is programmable from /24 to /80. SYSCLK9: 1/12-rate clock for SmartReflex. SYSCLK11: 1/6-rate clock for PSC only. Only SYSCLK2, SYSCLK5 and SYSCLK8 are programmable on theTMS320C6654 device. Note--In case any of the other programmable SYSCLKs are set slower than 1/64 rate, then SYSCLK8 (SLOW_SYSCLK) needs to be programmed to either match, or be slower than, the slowest SYSCLK in the system. PRODUCT PREVIEW 7.5.1.2 Main PLL Controller Operating Modes The Main PLL controller has two modes of operation: bypass mode and PLL mode. The mode of operation is determined by BYPASS bit of the PLL Secondary control register (SECCTL). In PLL mode, SYSCLK1 is generated from the PLL output using the values set in PLLM and PLLD bit fields in the MAINPLLCTL0 register. In bypass mode, PLL input is fed directly out as SYSCLK1. All hosts must hold off accesses to the DSP while the frequency of its internal clocks is changing. A mechanism must be in place such that the DSP notifies the host when the PLL configuration has completed. 7.5.1.3 Main PLL Stabilization, Lock, and Reset Times The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to become stable after device powerup. The PLL should not be operated until this stabilization time has expired. The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST = 1), in order for the PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For the Main PLL reset time value, see Table 7-13. The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1 with PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). The Main PLL lock time is given in Table 7-13.

When coming out of power-on reset, DDR3 PLL is programmed to a valid frequency during the boot config before being enabled and used. DDR3 PLL power is supplied externally via the Main PLL power-supply pin (AVDDA2). An external EMI filter circuit must be added to all PLL supplies. See the Hardware Design Guide for KeyStone Devices in ``Related Documentation from Texas Instruments'' on page 64. For the best performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or components other than those shown. For reduced PLL jitter, maximize the spacing between switching signal traces and the PLL external components (C1, C2, and the EMI Filter).

DDR3 PLL can be controlled using the DDR3PLLCTL0 and DDR3PLLCTL1 registers located in the Bootcfg module. These MMRs exist inside the Bootcfg space. To write to these registers, software should go through an un-locking sequence using KICK0/KICK1 registers. For suggested configurable values see section 3.3.4 ``Kicker Mechanism (KICK0 and KICK1) Register'' on page 71 for the address location of the registers and locking and unlocking sequences for accessing the registers.

The DDR3 PLL is affected by power-on reset. During power-on resets, the internal clocks of the DDR3 PLL are affected as described in Section 7.4 ``Reset Controller'' on page 119. DDR3 PLL is unlocked only during the power-up sequence and is locked by the time the RESETSTAT pin goes high. It does not lose lock during any of the other resets. 7.6.3 DDR3 PLL Initialization Sequence The Main PLL and PLL Controller must always be initialized prior to the DDR3 PLL. The sequence shown below must be followed to initialize the DDR3 PLL. 1. In DDR3PLLCTL1, write ENSAT = 1 (for optimal PLL operation) 2. In DDR3PLLCTL0, write BYPASS = 1 (set the PLL in Bypass) 3. In DDR3PLLCTL1, write PLLRST = 1 (PLL is reset) 4. Program PLLM and PLLD in DDR3PLLCTL0 register 5. Program BWADJ[7:0] in DDR3PLLCTL0 and BWADJ[11:8] in DDR3PLLCTL1 register. BWADJ value must be set to ((PLLM + 1) >> 1) - 1) 6. Wait for at least 5 s based on the reference clock (PLL reset time) 7. In DDR3PLLCTL1, write PLLRST = 0 (PLL reset is released) 8. Wait for at least 500 *REFCLK cycles * (PLLD + 1) (PLL lock time) 9. In DDR3PLLCTL0, write BYPASS = 0 (switch to PLL mode) 140 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 7.6.4 DDR3 PLL Input Clock Electrical Data/Timing Table 7-29 DDR3 PLL DDRSYSCLK1(N|P) Timing Requirements (see Figure 7-24 and Figure 7-20) No. Min Max 3.2 25 Unit DDRCLK[P:N] tc(DDRCLKN) Cycle time _ DDRCLKN cycle time ns 1 tc(DDRCLKP) Cycle time _ DDRCLKP cycle time 3.2 25 ns 3 tw(DDRCLKN) Pulse width _ DDRCLKN high 0.45*tc(DDRCLKN) 0.55*tc(DDRCLKN) ns 2 tw(DDRCLKN) Pulse width _ DDRCLKN low 0.45*tc(DDRCLKN) 0.55*tc(DDRCLKN) ns 2 tw(DDRCLKP) Pulse width _ DDRCLKP high 0.45*tc(DDRCLKP) 0.55*tc(DDRCLKP) ns 3 tw(DDRCLKP) Pulse width _ DDRCLKP low 0.45*tc(DDRCLKP) 0.55*tc(DDRCLKP) ns 4 tr(DDRCLKN_250mv) Transition time _ DDRCLKN rise time (250 mV) 50 350 ps 4 tf(DDRCLKN_250mv) Transition time _ DDRCLKN fall time (250 mV) 50 350 ps 4 tr(DDRCLKP_250mv) Transition time _ DDRCLKP rise time (250 mV) 50 350 ps 4 tf(DDRCLKP_250mv) Transition time _ DDRCLKP fall time (250 mV) 50 350 ps 5 tj(DDRCLKN) Jitter, peak_to_peak _ periodic DDRCLKN 0.025*tc(DDRCLKN) ps 5 tj(DDRCLKP) Jitter, peak_to_peak _ periodic DDRCLKP 0.025*tc(DDRCLKP) ps Peripheral Information and Electrical Specifications 141 End of Table 7-29 Figure 7-24 DDR3 PLL DDRCLK Timing 1 2 3 DDRCLKN DDRCLKP 4 Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions 5 PRODUCT PREVIEW 1 TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 7.7 Enhanced Direct Memory Access (EDMA3) Controller The primary purpose of the EDMA3 is to service user-programmed data transfers between two memory-mapped slave endpoints on the device. The EDMA3 services software-driven paging transfers (e.g., data movement between external memory and internal memory), performs sorting or subframe extraction of various data structures, services event driven peripherals, and offloads data transfers from the device CPU. There is one EDMA Channel Controller on the C6654 DSP, EDMA3_CC. It has four transfer controllers: TC0, TC1, TC2, and TC3. In the context of this document, TCx associated with CC is referred to as EDMA3_CC_TCx. Each of the transfer controllers has a direct connection to the switch fabric. Section 4.2 ``Switch Fabric Connections Matrix'' lists the peripherals that can be accessed by the transfer controllers. PRODUCT PREVIEW The EDMA3 Channel Controller includes the following features: * Fully orthogonal transfer description - 3 transfer dimensions: Array (multiple bytes) Frame (multiple arrays) Block (multiple frames) - Single event can trigger transfer of array, frame, or entire block - Independent indexes on source and destination * Flexible transfer definition: - Increment or FIFO transfer addressing modes - Linking mechanism allows for ping-pong buffering, circular buffering, and repetitive/continuous transfers, all with no CPU intervention - Chaining allows multiple transfers to execute with one event * 512 PaRAM entries - Used to define transfer context for channels - Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry * 64 DMA channels - Manually triggered (CPU writes to channel controller register), external event triggered, and chain triggered (completion of one transfer triggers another) * 8 Quick DMA (QDMA) channels - Used for software-driven transfers - Triggered upon writing to a single PaRAM set entry * 4 transfer controllers and 4 event queues with programmable system-level priority * Interrupt generation for transfer completion and error conditions * Debug visibility - Queue watermarking/threshold allows detection of maximum usage of event queues - Error and status recording to facilitate debug 7.7.1 EDMA3 Device-Specific Information The EDMA supports two addressing modes: constant addressing and increment addressing mode. Constant addressing mode is applicable to a very limited set of use cases; for most applications increment mode must be used. On the C6654 DSP, the EDMA can use constant addressing mode only with the Enhanced Viterbi-Decoder Coprocessor (VCP) and the Enhanced Turbo Decoder Coprocessor (TCP). Constant addressing mode is not supported by any other peripheral or internal memory in the DSP. Note that increment mode is supported by all peripherals, including VCP and TCP. For more information on these two addressing modes, see the Enhanced Direct 142 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com Memory Access 3 (EDMA3) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. For the range of memory addresses that include EDMA3 channel controller (EDMA3_CC) control registers and EDMA3 transfer controller (TC) control register see Section Table 2-2``Memory Map Summary'' on page 21.

The data FIFO is where the read return data read by the TC read controller from the source endpoint is stored and subsequently written out to the destination endpoint by the TC write controller. * BUSWIDTH: The width of the read and write data buses in bytes, for the TC read and write controller, respectively. This is typically equal to the bus width of the main TeraNet interface. * Default Burst Size (DBS): The DBS is the maximum number of bytes per read/write command issued by a transfer controller. * DSTREGDEPTH: This determines the number of Destination FIFO register set. The number of Destination FIFO register set for a transfer controller determines the maximum number of outstanding transfer requests. All four parameters listed above are specified by the design of the device. Table 7-31 provides the configuration of the EDMA3 transfer controller present on the device.

DMA channels can be triggered by synchronization events generated by system peripherals. The following tables lists the source of the synchronization event associated with each of the EDMA3_CC DMA channels. On the C6654, the association of each synchronization event and DMA channel is fixed and cannot be reprogrammed. For more detailed information on the EDMA3 module and how EDMA3 events are enabled, captured, processed, prioritized, linked, chained, and cleared, etc., see the Enhanced Direct Memory Access 3 (EDMA3) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64.

The interrupt controller allows for up to 128 system events to be programmed to any of the twelve CPU interrupt inputs (CPUINT4 - CPUINT15), the CPU exception input (EXCEP), or the advanced emulation logic. The 128 system events consist of both internally-generated events (within the CorePac) and chip-level events. Additional system events are routed to each of the C66x CorePacs to provide chip-level events that are not required as CPU interrupts/exceptions to be routed to the interrupt controller as emulation events. Additionally, error-class events or infrequently used events are also routed through the system event router to offload the C66x CorePac interrupt selector. This is accomplished through CIC blocks, CIC[1:0]. This is clocked using CPU/6. PRODUCT PREVIEW The event controllers consist of simple combination logic to provide additional events to the C66x CorePacs, plus the EDMA3_CC and CIC0 provide 12 additional events as well as 8 broadcast events to the C66x CorePacs, CIC1 provides 18 additional events to EDMA3_CC. There are a large amount of events on the chip level. The chip level CIC provides a flexible way to combine and remap those events. Multiple events can be combined to a single event through chip level CIC. However, an event can only be mapped to a single event output from the chip level CIC. The chip level CIC also allows the software to trigger system event through memory writes. The broadcast events to C66x CorePacs can be used for synchronization among multiple cores, inter-processor communication purposes, etc. For more details on the CIC features, please refer to the Chip Interrupt Controller (CIC) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. Note--Modules such as MPU, Tracer, and BOOT_CFG have level interrupts and EOI handshaking interface. The EOI value is 0 for MPU, Tracer, and BOOT_CFG. Figure 7-25 shows the C6654 interrupt topology.

QMS_PKTDMA is assigned with 88,89,90,91, but only 88-89 are actually used. There are two master ID values are assigned for the QM_second master port, one master ID for external linking RAM and the other one for the PDSP/MCDM accesses. 2 The master ID for MSMC is for the transactions initiated by MSMC internally and sent to the DDR. 3 All Tracers are set to the same master ID and bit 7 of the master ID needs to be 1. 7.9.1 MPU Registers PRODUCT PREVIEW This section

The DDR3 external bus interfaces only to DDR3 SDRAM devices; it does not share the bus with any other types of peripherals. 7.10.1 DDR3 Memory Controller Device-Specific Information The TMS320C6654 includes one 32-bit wide 1.5-V DDR3 SDRAM EMIF interface. The DDR3 interface can operate at 800 Mega Transfers per Second (MTS) and 1033 MTS. The DDR3 electrical requirements are fully specified in the DDR Jedec Specification JESD79-3C. Standard DDR3 SDRAMs are available in 8- and 16-bit versions, allowing for the following bank topologies to be supported by the interface: * 36-bit: Three 16-bit SDRAMs (including 4 bits of ECC) * 36-bit: Five 8-bit SDRAMs (including 4 bits of ECC) * 32-bit: Two 16-bit SDRAMs * 32-bit: Four 8-bit SDRAMs * 16-bit: One 16-bit SDRAM * 16-bit: Two 8-bit SDRAM The approach to specifying interface timing for the DDR3 memory bus is different than on other interfaces such as I2C or SPI. For these other interfaces, the device timing was specified in terms of data manual specifications and I/O buffer information specification (IBIS) models. For the DDR3 memory bus, the approach is to specify compatible DDR3 devices and provide the printed circuit board (PCB) solution and guidelines directly to the user. A race condition may exist when certain masters write data to the DDR3 memory controller. For example, if master A passes a software message via a buffer in external memory and does not wait for an indication that the write completes, before signaling to master B that the message is ready, when master B attempts to read the software message, then the master B read may bypass the master A write and, thus, master B may read stale data and, therefore, receive an incorrect message. Some master peripherals (e.g., EDMA3 transfer controllers with TCCMOD=0) will always wait for the write to complete before signaling an interrupt to the system, thus avoiding this race condition. For masters that do not have a hardware specification of write-read ordering, it may be necessary to specify data ordering via software. If master A does not wait for indication that a write is complete, it must perform the following workaround: 1. Perform the required write to DDR3 memory space. 2. Perform a dummy write to the DDR3 memory controller module ID and revision register. 3. Perform a dummy read to the DDR3 memory controller module ID and revision register. 4. Indicate to master B that the data is ready to be read after completion of the read in step 3. The completion of the read in step 3 ensures that the previous write was done.

The DDR3 electrical requirements are fully specified in the DDR3 Jedec Specification JESD79-3C. TI has performed the simulation and system characterization to ensure all DDR3 interface timings in this solution are met; therefore, no electrical data/timing information is supplied here for this interface. Note--TI supports only designs that follow the board design guidelines outlined in the application report. 7.11 I2C Peripheral 2 PRODUCT PREVIEW The inter-integrated circuit (I C) module provides an interface between DSP and other devices compliant with Philips Semiconductors Inter-IC bus (I2C bus) specification version 2.1 and connected by way of an I2C bus. External components attached to this 2-wire serial bus can transmit/receive up to 8-bit data to/from the DSP 2 through the I C module. 2 7.11.1 I C Device-Specific Information 2 The TMS320C6654 device includes an I C peripheral module. 2 Note--When using the I C module, ensure there are external pullup resistors on the SDA and SCL pins. 2 The I C modules on the C6654 may be used by the DSP to control local peripheral ICs (DACs, ADCs, etc.) or may be used to communicate with other controllers in a system or to implement a user interface. 2 2 The I C port is compatible with Philips I C specification revision 2.1 (January 2000) and supports: * Fast mode up to 400 Kbps (no fail-safe I/O buffers) * Noise filter to remove noise 50 ns or less * 7-bit and 10-bit device addressing modes * Multi-master (transmit/receive) and slave (transmit/receive) functionality * Events: DMA, interrupt, or polling * Slew-rate limited open-drain output buffers 182 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com 2 Figure 7-31 shows a block diagram of the I C module.

The UART is based on the industry standard TL16C550 asynchronous communications element, which in turn is a functional upgrade of the TL16C450. Functionally similar to the TL16C450 on power up (single character or TL16C450 mode), the UART can be placed in an alternate FIFO (TL16C550) mode. This relieves the DSP of excessive software overhead by buffering received and transmitted characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per byte for the receiver FIFO. PRODUCT PREVIEW The UART performs serial-to-parallel conversions on data received from a peripheral device and parallel-to-serial conversion on data received from the DSP. The DSP can read the UART status at any time. The UART includes control capability and a processor interrupt system that can be tailored to minimize software management of the communications link. For more information on UART, see the Universal Asynchronous Receiver/Transmitter (UART) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64.

The EMAC supports 10Base-T (10 Mbits/second [Mbps]), and 100BaseTX (100 Mbps), in half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with hardware flow control and quality-of-service (QOS) support. Deviating from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER. Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame will be detected as an error by the network. The EMAC control module is the main interface between the device core processor, the MDIO module, and the EMAC module. The relationship between these three components is shown in Figure 7-44. The EMAC control module contains the necessary components to allow the EMAC to make efficient use of device memory, plus it controls device interrupts. The EMAC control module incorporates 8K-bytes of internal RAM to hold EMAC buffer descriptors.

TI has performed the simulation and system characterization to ensure all EMAC and SGMII interface timings in this solution are met; therefore, no electrical data/timing information is supplied here for this interface. Note--TI supports only designs that follow the board design guidelines outlined in the application report. 7.17 Management Data Input/Output (MDIO) The management data input/output (MDIO) module implements the 802.3 serial management interface to interrogate and controls up to 32 Ethernet PHY(s) connected to the device, using a shared two-wire bus. Application software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the GbE switch subsystem, retrieve the negotiation results, and configure required parameters in the GbE switch subsystem module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from the core processor. For more information, see the Gigabit Ethernet (GbE) Subsystem for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. The EMAC control module is the main interface between the device core processor, the MDIO module, and the EMAC module. The relationship between these three components is shown in Figure 7-44.

Timer0 is dedicated to the CorePac as a watchdog timer and can also be used as a general-purpose timer. Each of the other seven timers can also be configured as a general-purpose timer only, programmed as a 64-bit timer or as two separate 32-bit timers. When operating in 32-bit mode, the timer is split into two independent 32-bit timers. Each timer is made up of two 32-bit counters: a high counter and a low counter. The timer pins, TINPLx and TOUTLx are connected to the low counter. The timer pins, TINPHx and TOUTHx are connected to the high counter. When operating in watchdog mode, the timer counts down to 0 and generates an event. It is a requirement that software writes to the timer before the count expires, after which the count begins again. If the count ever reaches 0, the timer event output is asserted. Reset initiated by a watchdog timer can be set by programming ``Reset Type Status Register (RSTYPE)'' on page 133 and the type of reset initiated can set by programming ``Reset Configuration Register (RSTCFG)'' on page 134. For more information, see the 64-bit Timer (Timer 64) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. 7.18.2 Timers Electrical Data/Timing The tables and figure below describe the timing requirements and switching characteristics of Timer0 through Timer7 peripherals.

The Semaphore enforces atomic accesses to shared chip-level resources so that the read-modify-write sequence is not broken. The semaphore block has unique interrupts to each of the cores to identify when that core has acquired the resource. Semaphore resources within the module are not tied to specific hardware resources. It is a software requirement to allocate semaphore resources to the hardware resource(s) to be arbitrated. The Semaphore module supports 8 masters and contains 32 semaphores to be used within the system. There are two methods of accessing a semaphore resource: * Direct Access: A core directly accesses a semaphore resource. If free, the semaphore will be granted. If not, the semaphore is not granted. * Indirect Access: A core indirectly accesses a semaphore resource by writing it. Once it is free, an interrupt notifies the CPU that it is available.

This capability can be used to debug complex problems as well as understand performance characteristics of user applications. AET provides the following capabilities: * Hardware Program Breakpoints: specify addresses or address ranges that can generate events such as halting the processor or triggering the trace capture. * Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate events such as halting the processor or triggering the trace capture. * Counters: count the occurrence of an event or cycles for performance monitoring. * State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to precisely generate events for complex sequences. For more information on AET, see the following documents in ``Related Documentation from Texas Instruments'' on page 64: * Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report * Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded Microprocessor Systems application report 7.21.2 Trace The C6654 device supports Trace. Trace is a debug technology that provides a detailed, historical account of application code execution, timing, and data accesses. Trace collects, compresses, and exports debug information for analysis. Trace works in real-time and does not impact the execution of the system.

The boundary scan supported allows for an asynchronous TRST and only the 5 baseline JTAG signals (e.g., no EMU[1:0]) required for boundary scan. Most interfaces on the device follow the Boundary Scan Test Specification (IEEE1149.1), while all of the SerDes (SGMII) support the AC-coupled net test defined in AC-Coupled Net Test Specification (IEEE1149.6). It is expected that all compliant devices are connected through the same JTAG interface, in daisy-chain fashion, in accordance with the specification. The JTAG interface uses 1.8-V LVCMOS buffers, compliant with the Power Supply Voltage and Interface Standard for Nonterminated Digital Integrated Circuit Specification (EAI/JESD8-5). 7.21.3.1 IEEE 1149.1 JTAG Compatibility Statement For maximum reliability, the C6654 DSP includes an internal pulldown (IPD) on the TRST pin to ensure that TRST will always be asserted upon power up and the DSP's internal emulation logic will always be properly initialized when this pin is not routed out. JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG controllers may not drive TRST high but expect the use of an external pullup resistor on TRST.

It is designed to interface cleanly with high-speed analog-to-digital converters (ADCs) or digital-to-analog converters (DACs) with up to 16-bit data width (per channel). It may also be interconnected with field-programmable gate arrays (FPGAs) or other UPP devices to achieve high-speed digital data transfer. It can operate in receive mode, transmit mode, or duplex mode, in which its individual channels operate in opposite directions. PRODUCT PREVIEW The UPP peripheral includes an internal DMA controller to maximize throughput and minimize CPU overhead during high-speed data transmission. All UPP transactions use the internal DMA to provide data to or retrieve data from the I/O channels. The DMA controller includes two DMA channels, which typically service separate I/O channels. The UPP peripheral also supports data interleave mode, in which all DMA resources service a single I/O channel. In this mode, only one I/O channel may be used. The features of the UPP include: * Programmable data width per channel (from 8 bits to 16 bits inclusive) * Programmable data justification - Right-justify with 0 extend - Right-justify with sign extend - Left-justify with 0 fill * Supports multiplexing of interleaved data during SDR transmit * Optional frame START signal with programmable polarity * Optional data ENABLE signal with programmable polarity * Optional synchronization WAIT signal with programmable polarity * Single Data Rate (SDR) or Double data Rate (DDR, interleaved) interface - Supports multiplexing of interleaved data during SDR transmit - Supports demultiplexing and multiplexing of interleaved data during DDR transfers For more information, see the Universal Parallel Port (UPP) for KeyStone Devices User Guide in ``Related Documentation from Texas Instruments'' on page 64. 7.23.1 UPP Register Descriptions Table 7-84 Universal Parallel Port (UPP) Registers (Part 1 of 2) Byte Address Acronym Register Description 0x0258 0000 UPPID UPP Peripheral Identification Register 0x0258 0004 UPPCR UPP Peripheral Control Register 0x0258 0008 UPDLB UPP Digital Loopback Register 0x0258 0010 UPCTL UPP Channel Control Register 0x0258 0014 UPICR UPP Interface Configuration Register 0x0258 0018 UPIVR UPP Interface Idle Value Register 0x0258 001C UPTCR UPP Threshold Configuration Register 0x0258 0020 UPISR UPP Interrupt Raw Status Register 0x0258 0024 UPIER UPP Interrupt Enabled Status Register 0x0258 0028 UPIES UPP Interrupt Enable Set Register 0x0258 002C UPIEC UPP Interrupt Enable Clear Register 0x0258 0030 UPEOI UPP End-of-Interrupt Register 0x0258 0040 UPID0 UPP DMA Channel I Descriptor 0 Register 212 Peripheral Information and Electrical Specifications Copyright 2012 Texas Instruments Incorporated TI Confidential--NDA Restrictions TMS320C6654 Fixed and Floating-Point Digital Signal Processor SPRS841--March 2012 www.ti.com Universal Parallel Port (UPP) Registers (Part 2 of 2) Byte Address Acronym Register Description 0x0258 0044 UPID1 UPP DMA Channel I Descriptor 1 Register 0x0258 0048 UPID2 UPP DMA Channel I Descriptor 2 Register 0x0258 0050 UPIS0 UPP DMA Channel I Status 0 Register 0x0258 0054 UPIS1 UPP DMA Channel I Status 1 Register 0x0258 0058 UPIS2 UPP DMA Channel I Status 2 Register 0x0258 0060 UPQD0 UPP DMA Channel Q Descriptor 0 Register 0x0258 0064 UPQD1 UPP DMA Channel Q Descriptor 1 Register 0x0258 0068 UPQD2 UPP DMA Channel Q Descriptor 2 Register 0x0258 0070 UPQS0 UPP DMA Channel Q Status 0 Register 0x0258 0074 UPQS1 UPP DMA Channel Q Status 1 Register 0x0258 0078 UPQS2 UPP DMA Channel Q Status 2 Register End of Table 7-84 Table 7-85 UPP Timing Requirements (see Figure 7-53, Figure 7-54, Figure 7-55, Figure 7-56) No. Min 1 tc(INCLK) Cycle time, CHn_CLK 2 tw(INCLKH) Pulse width, CHn_CLK high 3 tw(INCLKL) Pulse width, CHn_CLK low 4 tsu(STV-INCLKH) Setup time, CHn_START valid before CHn_CLK high 5 th(INCLKH-STV) Hold time, CHn_START valid after CHn_CLK high 6 tsu(ENV-INCLKH) Setup time, CHn_ENABLE valid before CHn_CLK high 7 th(INCLKH-ENV) Hold time, CHn_ENABLE valid after CHn_CLK high 8 tsu(DV-INCLKH) Setup time, CHn_DATA/XDATA valid before CHn_CLK high 9 th(INCLKH-DV) Hold time, CHn_DATA/XDATA valid after CHn_CLK high 10 tsu(DV-INCLKL) Setup time, CHn_DATA/XDATA valid before CHn_CLK low 11 th(INCLKL-DV) Hold time, CHn_DATA/XDATA valid after CHn_CLK low SDR mode 13.33 DDR mode 26.66 SDR mode 5 DDR mode 10 SDR mode 5 DDR mode 10 Max Unit ns ns ns 4 ns 0.8 ns 4 ns 0.8 ns 4 ns 0.8 ns 4 ns 0.8 ns 19 su(WTV-INCLKL) Setup time, CHn_WAIT valid before CHn_CLK high 10 ns 20 th(INCLKL-WTV) Hold time, CHn_WAIT valid after CHn_CLK high 0.8 ns 21 tc(2xTXCLK) Cycle time, 2xTXCLK input clock (1) 6.66 ns End of Table 7-85 1 2xTXCLK is an alternate transmit clock source that must be at least 2 times the required UPP transmit clock rate (as it is divided down by 2 inside the UPP). 2xTXCLK has no specified skew relationship to the CHn_CLOCK and therefore is not shown in the timing diagram.
