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.

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 50-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 TMS320C6671 DSP is a highest-performance fixed/floating-point single-core DSP that is based on TI's

KeyStone multicore architecture. It is pin-for-pin compatible with the TMS320C6678 / 6674 / 6672 multicore

high-performance DSPs. Incorporating the new and innovative C66x DSP core, this device can run at a core speed

of up to 1.25 GHz. 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 TMS320C6671 DSP offers 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 4× 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 40 GMACS/core and 20GFLOPS/core (@1.25 GHz operating frequency). 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 C6671 DSP integrates a large amount of on-chip memory. In addition to 32KB of L1 program and data cache,

there is 512KB of dedicated memory that can be configured as mapped RAM or cache. The device also integrates

4096KB of Multicore Shared Memory that can be used as a shared L2 SRAM and/or shared L3 SRAM. All L2

memories incorporate error detection and error correction. For fast access to external memory, this device includes

a 64-bit DDR-3 external memory interface (EMIF) running at 1600 MHz and has ECC DRAM support.

This family supports a plethora of high speed standard interfaces including RapidIO ver 2, PCI Express Gen2, and

Gigabit Ethernet, as well as an integrated Ethernet switch. It also includes I2C, UART, Telecom Serial Interface Port

(TSIP), and a 16-bit EMIF, along with general purpose CMOS IO. For high throughput, low latency communication

between devices or with an FPGA, this device also sports a 50-Gbaud full-duplex interface called HyperLink. Adding

to the network awareness of this device is a network co-processor that includes both packet and optional security

acceleration. The packet accelerator can process up to 1.5 M packets/s and enables a single IP address to be used for

the entire C6671 device. It also provides L2 to L4 classification, along with checksum and QoS capabilities.

The C6671 device has a complete set of development tools, which includes: an enhanced C compiler, an assembly

optimizer to simplify programming and scheduling, and a Windows® debugger interface for visibility into source

code execution.

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.

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 × 32 bit

multiplies, sixteen 16 × 16 bit multiplies, four 16 × 32 bit multiplies, four 8 × 8 bit multiplies, four 8 × 8 bit multiplies

with add operations, and four 16 × 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 × 16 bit complex multiply with or without rounding

capabilities, two 16 × 16 bit complex multiplies with rounding capability, and a 32 × 32 bit complex multiply with

rounding capability. The C66x can also perform two 16 × 16 bit and one 32 × 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 × 2] complex vector by a [2 × 2] complex matrix per cycle with or without rounding capability.

A version also exists allowing multiplication of the conjugate of a [1 × 2] vector with a [2 × 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

Fixed and Floating-Point Digital Signal Processor

SPRS756D—April 2013

TMS320C6671

www.ti.com

operands, instructions were also added to double the number of these conversions that can be done. 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.

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.

For more details on the C66x DSP and its enhancements over the C64x+ and C674x architectures, see the following

2.4 Boot Sequence

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 the 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 129. 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 Table 2-3.

The C6671 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 73.

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[3:0] 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 CorePac0is 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. See the Bootloader for the C66x DSP User Guide in ‘‘Related

Documentation from Texas Instruments’’ on page 73 for more details.

•Secure ROM Boot - On secure devices, the C66x CorePac0is released from reset and begin executing from

secure ROM. Software in the secure ROM will free up internal RAM pages, after which the C66x CorePac0

initiates the boot process. The C66x CorePac0 performs any authentication and decryption required on the

bootloaded image prior to beginning execution.

The boot process performed by the C66x CorePac0 in public ROM boot and secure ROM boot are determined by

the BOOTMODE[12:0] value in the DEVSTAT register. The C66x CorePac0 reads this value, and then executes the

associated boot process in software. Figure 2-2 shows the bits associated with BOOTMODE[12:0].

definitions depend on the boot mode

2.5.2.1 No Boot/ EMIF16 Boot Device Configuration

2.5.2.2 Serial Rapid I/O Boot Device Configuration

The device ID is always set to 0xff (8-bit node IDs) or 0xffff (16 bit node IDs) at power-on reset.

In SRIO boot mode, the message mode will be enabled by default. If use of the memory reserved for received

messages is required and reception of messages cannot be prevented, the master can disable the message mode by

writing to the boot table and generating a boot restart.

2.5.4 PLL Boot Configuration Settings

The PLL default settings are determined by the BOOTMODE[12:10] bits. The table below shows settings for various

input clock frequencies.

OUTPUT_DIVIDE is the value of the field of SECCTL[22:19]. This will set the PLL to the maximum clock setting

for the device (with OUTPUT_DIVIDE=2, by default).

CLK = CLKIN × ((PLLM+1) ÷ (OUTPUT_DIVIDE × (PLLD+1)))

The configuration for the PASS PLL is also shown. The PASS PLL is configured with these values only if the Ethernet

boot mode is selected with the input clock set to match the main PLL clock (not the PASS clock). See Table 2-4 for

details on configuring Ethernet boot mode. The output from the PASS PLL goes through an on-chip divider to

reduce the operating frequency before reaching the NETCP. The PASS PLL generates 1050 MHz, and after the chip

divider (=3), feeds 350 MHz to the NETCP.

The Main PLL is controlled using a PLL controller and a chip-level MMR. The DDR3 PLL and PASS PLL are

controlled by chip level MMRs. For details on how to set up the PLL see section 7.5 ‘‘Main PLL and PLL Controller’’

on page 136. For details on the operation of the PLL controller module, see the Phase Locked Loop (PLL) for KeyStone

Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73.

2.6 Second-Level Bootloaders

Any of the boot modes can be used to download a second-level bootloader. A second-level bootloader allows for any

level of customization to current boot methods as well as the definition of a completely customized boot.

2.8 Terminal Functions

The terminal functions table (Table 2-26) identifies the external signal names, the associated pin (ball) numbers, the

pin type (I, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and gives functional pin

descriptions. This table is arranged by function. The power terminal functions table (Table 2-27) lists the various

power supply pins and ground pins and gives functional pin descriptions. Table 2-28 shows all pins arranged by

signal name. Table 2-29 shows all pins arranged by ball number.

There are 17 pins that have a secondary function as well as a primary function. The secondary function is indicated

with a dagger (†).

For more detailed information on device configuration, peripheral selection, multiplexed/shared pins, and

pullup/pulldown resistors, see section 3.4 ‘‘Pullup/Pulldown Resistors’’ on page 94.

Use the symbol definitions in Table 2-25 when reading Table 2-26.

Internal 100-μA pulldown or pullup is provided for this terminal. In most systems, a 1-k resistor can

be used to oppose the IPD/IPU. For more detailed information on pulldown/pullup resistors and

situations in which external pulldown/pullup resistors are required, see Hardware Design Guide for

KeyStone Devices in ‘‘Related Documentation from Texas Instruments’’ on page 73.

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 C6671 device, TI offers an

extensive line of development tools for the TMS320C6000™ 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 Studio™ Integrated Development Environment (IDE).

The following products support development of C6000™ DSP-based applications:

•Software Development Tools:

–Code Composer Studio™ Integrated Development Environment (IDE), including Editor C/C++/Assembly

Code Generation, and Debug plus additional development tools.

–Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software

needed to support any DSP application.

•Hardware Development Tools:

–Extended Development System (XDS™) Emulator (supports C6000™ 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.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for

example, CYP), the temperature range (for example, blank is the default case temperature range), and the device

3 Device Configuration

On the TMS320C6671 device, certain device configurations like boot mode and endianess, are selected at device

power-on reset. The status of the peripherals (enabled/disabled) is determined after device power-on reset.

3.1 Device Configuration at Device 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 94.

3.2 Peripheral Selection After Device Reset

Several of the peripherals on the TMS320C6671 are controlled by the Power Sleep Controller (PSC). By default, the

PCIe, SRIO, and HyperLink are held in reset and clock-gated. The memories in these modules are also in a

low-leakage sleep mode. Software is required to turn these memories on. The software enables the modules (turns

on clocks and de-asserts reset) before these modules 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 73.

3.3 Device State Control Registers

The TMS320C6671 device has a set of registers that are used to provide the status or configure certain parts of its

peripherals. These registers are shown in Table 3-2.

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). 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 75 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.

The kicker mechanism is unlocked by the ROM code. Do not write any other different values afterward to these

registers because that will lock the kicker mechanism and block any writes to Bootcfg registers.

3.3.5 DSP Boot Address (DSP_BOOT_ADDRn) Register

The DSP_BOOT_ADDRn register stores the initial boot fetch address of CorePac_n (n = core number). The fetch

address is the public ROM base address (for any boot mode) by default. DSP_BOOT_ADDRn register access should

be permitted to any master or emulator when the device is non-secure. CorePac will boot from that address when a

reset is performed. The DSP_BOOT_ADDRn register is shown in and described in .

3.3.6 LRESETNMI PIN Status (LRSTNMIPINSTAT) Register

The LRSTNMIPINSTAT Register is created in Boot Configuration to latch the status of LRESET and NMI based on

CORESEL. The LRESETNMI PIN Status Register is shownin Figure 3-4 and described in Table 3-6.

3.3.7 LRESETNMI PIN Status Clear (LRSTNMIPINSTAT_CLR) Register

3.3.8 Reset Status (RESET_STAT) Register

The reset status register (RESET_STAT) captures the status of Local reset (LRx) for each of the cores and also the

global device reset (GR). Software can use this information to take different device initialization steps, if desired.

• In case of Local reset: The LRx bits are written as 1 and GR bit is written as 0 only when the CorePac receives

an local reset without receiving a global reset.

• In case of Global reset: The LRx bits are written as 0 and GR bit is written as 1 only when a global reset is

asserted.

The Reset Status Register is shown in Figure 3-6 and described in Table 3-8.

3.3.9 Reset Status Clear (RESET_STAT_CLR) Register

The RESET_STAT bits can be cleared by writing 1 to the corresponding bit in the RESET_STAT_CLR register. The

3.3.10 Boot Complete (BOOTCOMPLETE) Register

The BOOTCOMPLETE register controls the BOOTCOMPLETE pin status. The purpose is to indicate the

completion of the ROM booting process. The Boot Complete Register is shown in Figure 3-8 and described in

Table 3-10.

The BCx bit indicates the boot complete status of the corresponding core. All BCx bits will be sticky bits — that is

they can be set only once by the software after device reset and they will be cleared to 0 on all device resets.

Boot ROM code will be implemented such that each core will set its corresponding BCx bit immediately before

branching to the predefined location in memory.

3.3.11 Power State Control (PWRSTATECTL) Register

The PWRSTATECTL register is controlled by the software to indicate the power-saving mode. ROM code reads this

3.3.12 NMI Event Generation to CorePac (NMIGRx) Register

NMIGRx registers are used for generating NMI events to the corresponding CorePac. The C6671 has

one NMIGRx register (NMIGR0). The NMIGR0 register generates an NMI event to CorePac0. Writing a 1 to the

NMIG field generates a NMI pulse. Writing a 0 has no effect and reads return 0 and have no other effect. The NMI

Even Generation to CorePac Register is shown in Figure 3-10 and described in Table 3-12.

3.3.13 IPC Generation (IPCGRx) Registers

IPCGRx are the IPC interrupt generation registers to facilitate inter CorePac interrupts.

The C6671 has one IPCGRx register (IPCGR0). This register can be used by external hosts or CorePacs to generate

interrupts to other CorePacs. A write of 1 to IPCG field of IPCGRx register will generate an interrupt pulse to

CorePac0.

3.3.14 IPC Acknowledgement (IPCARx) Registers

IPCARx are the IPC interrupt-acknowledgement registers to facilitate inter-CorePac core interrupts.

The C6671 has one IPCARx register (IPCAR0). 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 shown 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. The IPC Acknowledgement Register is shown in Figure 3-12

and described in Table 3-14.

3.3.15 IPC Generation Host (IPCGRH) Register

The IPCGRH register facilitates interrupts to external hosts. Operation and use of the IPCGRH register is the same

as for other IPCGR registers. The interrupt output pulse created by the IPCGRH register appears on device pin

HOUT.

The host interrupt output pulse is stretched so that it is asserted for four bootcfg clock (CPU/6) cycles followed by a

deassertion of four bootcfg clock cycles. Generating the pulse results in a pulse-blocking window that is eight

CPU/6-cycles long. Back to back writes to the IPCRGH register with the IPCG bit (bit 0) set, generates only one pulse

if the back-to-back writes to IPCGRH are less than the eight CPU/6 cycle window -- the pulse blocking window. In

order to generate back-to-back pulses, the back-to-back writes to the IPCGRH register must be greater than eight

CPU/6 cycle window. The IPC Generation Host Register is shown in Figure 3-13 and described in Table 3-15.

3.4 Pullup/Pulldown Resistors

Proper board design should ensure that input pins to the device always be at a valid logic level and not floating. 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.

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 TMS320C6671 device, see Section 6.3 ‘‘Electrical Characteristics’’ on page 115.

To determine which pins on the device include internal pullup/pulldown resistors, see Table 2-26 ‘‘Terminal

Functions — Signals and Control by Function’’ on page 47.

4 System Interconnect

On the TMS320C6671 device, the C66x CorePac, the EDMA3 transfer controllers, 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

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.

The C66x CorePac, the EDMA3 traffic controllers, 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 controllers, SRIO, and Network Coprocessor packet

DMA. Examples of slaves include the SPI, UART, and I2C.

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. Some peripherals require a bridge to connect to the data

TeraNet. The configuration TeraNet, is mainly used to access peripheral registers. The configuration TeraNet

connects masters to slaves via configuration buses. As with the data TeraNet, some peripherals require the use of a

bridge to interface to the configuration TeraNet. Note that the data TeraNet also connects to the configuration

TeraNet. For more details see 4.2 ‘‘Switch Fabric Connections’’.

4.3 Bus Priorities

The priority level of all master peripheral traffic is defined at the TeraNet boundary. 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.

All other masters 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.

The packet DMA secondary port is one master port that does not have priority allocation register inside the IP. The

priority level for transaction from this master port is described by PKTDMA_PRI_ALLOC register in Figure 4-5 and

Table 4-4.

For all other modules, see the respective User Guides in “Related Documentation from Texas Instruments” on

page 73 for programmable priority registers.

5.1 Memory Architecture

The C66x CorePac of the TMS320C6671 device contains a 512KB level-2 memory (L2), a 32KB level-1 program

memory (L1P), and a 32KB level-1 data memory (L1D). The device also contain a 4096KB multicore shared memory

(MSM). All memory on the C6671 has a unique location in the memory map (see Table 2-2 ‘‘Memory Map

Summary’’ on page 21.

After device reset, L1P and L1D cache are configured as all cache, by default. The L1P and L1D cache can be

reconfigured via software through the L1PMODE field of the L1P Configuration Register (L1PCFG) and the

L1DMODE field of the L1D Configuration Register (L1DCFG) of the C66x CorePac. L1D is a two-way

set-associative cache, while L1P is a direct-mapped cache.

The on-chip bootloader changes the reset configuration for L1P and L1D. For more information, see the Bootloader

5.1.3 L2 Memory

The L2 memory configuration for the C6671 device is as follows:

• Total memory size is 4096KB

• Each core contains 512KB of memory

• Local starting address for each core is 0080 0000h

L2 memory can be configured as all SRAM, all 4-way set-associative cache, or a mix of the two. The amount of L2

memory that is configured as cache is controlled through the L2MODE field of the L2 Configuration Register

(L2CFG) of the C66x CorePac. Figure 5-4 shows the available SRAM/cache configurations for L2. By default, L2 is

configured as all SRAM after device reset.

Figure 5-4 L2 Memory Configurations

Global addresses are accessible to all masters in the system. In addition, local memory can be accessed directly by

the associated processor through aliased addresses, where the eight MSBs are masked to zero. The aliasing is handled

within the C66x CorePac and allows for common code to be run unmodified on multiple cores. 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, as mentioned, this 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.

5.1.4 MSM SRAM

The MSM SRAM configuration for the C6671 device is as follows:

• Memory size is 4096KB

• The MSM SRAM can be configured as shared L2 and/or shared L3 memory

• Allows extension of external addresses from 2GB to up to 8GB

• Has built in memory protection features

The MSM SRAM is always configured as all SRAM. When configured as a shared L2, its contents can be cached in

L1P and L1D. When configured in shared L3 mode, it’s contents can be cached in L2 also. For more details on

external memory address extension and memory protection features, see the Multicore Shared Memory Controller

(MSMC) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73.

5.1.5 L3 Memory

The L3 ROM on the device is 128KB. The ROM contains software used to boot the device. There is no requirement

to block accesses from this portion to the ROM.

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.

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 zero, 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. For more information on memory protection for L1D, L1P, and L2, see the C66x CorePac User

Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73.

Table 5-1 Available Memory Page Protection Schemes

AIDx Bit Local Bit Description

0 0 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.

5.3 Bandwidth Management

When multiple requestors contend for a single C66x CorePac resource, the conflict is resolved by granting access to

the highest priority requestor. The following four resources are managed by the Bandwidth Management control

hardware:

• Level 1 Program (L1P) SRAM/Cache

• Level 1 Data (L1D) SRAM/Cache

• Level 2 (L2) SRAM/Cache

• Memory-mapped registers configuration bus

The priority level for operations initiated within the C66x CorePac are declared through registers in the C66x

CorePac. 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 4.3 ‘‘Bus Priorities’’ on page 104 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 73.

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 C6671 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

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, AVDD1, AVDD2

4. DVDD15, VDDR1-4

The second sequence provides compatibility with other TI processors with the IO voltage starting before the core

voltages as shown below.

1. DVDD18, AVDD1, AVDD2

2. CVDD

3. CVDD1, VDDT1-2

4. DVDD15, VDDR1-4

The clock input buffers for CORECLK, DDRCLK, PASSCLK, SRIOSGMIICLK, PCIECLK and MCMCLK

use 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. REFCLK in the following section refers to

the clock input that has been selected as the source for the main PLL and SYSCLK1 refers to the main PLL output

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 TMS320C6671 for device initialization. POR may be

removed after the power has been stable for the required 100 μsec. 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.

REFCLK must always be active before POR can be removed. Core-before-IO power sequencing is defined in

Table 7-2.

Note—TI recommends a maximum of 100 ms between one power rail being valid, and the next power rail

in the sequence starting to ramp. Each supply must ramp monotonically and must reach a stable valid level

within 20ms.

• CVDD (core AVS) ramps up.

•POR

must be held low through the power stabilization phase. Because POR is low, all the core logic that has async reset (created from

POR) is put into the reset state.

• Once enabled, the power supply should ramp to its valid voltage level within 20 ms.

2a • CVDD1 (core constant) ramps at the same time or shortly following CVDD. Although ramping CVDD1 and CVDD simultaneously is

permitted, the voltage for CVDD1 must never exceed CVDD until after CVDD has reached a valid voltage.

• The purpose of ramping up the core supplies close to each other is to reduce crowbar current. CVDD1 should trail CVDD as this will

ensure that the WLs in the memories are turned off and there is no current through the memory bit cells. If, however, CVDD1 (core

constant) ramps up before CVDD (core AVS), then the worst-case current could be on the order of twice the specified draw of CVDD1.

• The maximum duration is 100ms.

2b • Once CVDD is valid, the clock drivers should be enabled. Although the clock inputs are not necessary at this time, they should either be

driven with a valid clock or be held in a static state with one leg high and one leg low.

2c • The DDRCLK and REFCLK may begin to toggle anytime between when CVDD is at a valid level and the setup time before POR goes high

specified by t6.

3 • Filtered versions of 1.8 V can ramp simultaneously with DVDD18.

• RESETSTAT is driven low once the DVDD18 supply is available.

• All LVCMOS input and bidirectional pins must not be driven or pulled high until DVDD18 is present. Driving an input or bidirectional pin

before DVDD18 is valid could cause damage to the device.

4a • DVDD15 (1.5 V) supply is ramped up after DVDD18 is valid. Although ramping DVDD18 and DVDD15 simultaneously is permitted, the

voltage for DVDD15 must never exceed DVDD18.

4b • RESET may be driven high any time after DVDD18 is at a valid level. In a POR-controlled boot, RESET must be high before POR is driven

high.

5•POR must continue to remain low for at least 100 μs after power has stabilized.

End Power Stabilization Phase

6 • Device initialization requires 500 REFCLK periods after the Power Stabilization Phase. The maximum clock period is 33.33 nsec, so a delay

of an additional 16 μs is required before a rising edge of POR. The clock must be active during the entire 16 μs.

7•RESETFULL

must be held low for at least 24 transitions of the REFCLK after POR has stabilized at a high level.

8 • The rising edge of the RESETFULL will remove the reset to the efuse farm allowing the scan to begin.

• Once device initialization and the efuse farm scan are complete, the RESETSTAT signal is driven high. This delay will be 10000 to 50000

clock cycles.

End Device Initialization Phase

7.2.1.2 IO-Before-Core Power Sequencing

The timing diagram for IO-before-core power sequencing is shown in Figure 7-2 and defined in Table 7-3.

Note—TI recommends a maximum of 100 ms between one power rail being valid, and the next power rail

in the sequence starting to ramp. Each supply must ramp monotonically and must reach a stable valid level

within 20ms.

7.2.1.3 Prolonged Resets

Holding the device in POR, RESETFULL, or RESET for long periods of time will affect the long term reliability of

the part. 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.

Table 7-3 IO Before Core Power Sequencing

•Because POR

is low, all the core logic having async reset (created from POR) are put into reset state once the core supply ramps. POR must

remain low through Power Stabilization Phase.

• RESETSTAT is driven low once the DVDD18 supply is available.

• All input and bidirectional pins must not be driven or pulled high until DVDD18 is present. Driving an input or bidirectional pin before

DVDD18 could cause damage to the device.

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 73.

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 TMS320C6671 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

TMS320C6671 device.

To guarantee maximizing performance and minimizing power consumption of the device, SmartReflex is required

to be implemented whenever the TMS320C6671 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.

For information on implementation of SmartReflex see the Power Management for KeyStone Devices application

report and the Hardware Design Guide for KeyStone Devices in ‘‘Related Documentation from Texas Instruments’’

on page 73.

7.3 Power Sleep Controller (PSC)

The Power Sleep Controller (PSC) controls overall device power by turning off unused power domains and gating

off clocks to individual peripherals and modules. 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 73.

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

global power/sleep controller (GPSC) is used to control the power gating of various power domains.

Cock gating to each logic block is managed by the local power/sleep controllers (LPSCs) of each module. For

modules with a dedicated clock or multiple clocks, the LPSC communicates with the PLL controller to enable and

disable that module's clock(s) at the source. For modules that share a clock with other modules, the LPSC controls

the clock gating.

7.4.1 Power-on Reset

Power-on reset is used to reset the entire device, including the test and emulation logic.

Power-on reset is initiated by the following

1. POR pin

2. RESETFULL pin

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 75).

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.

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

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.

The following sequence must be followed during a hard reset:

1. The RESET pin is pulled active low for a minimum of 24 CLKIN1 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.

7.4.3 Soft Reset

A soft reset will behave like a hard reset except that EMIF16 MMRs, DDR3 EMIF MMRs and the PCIe MMRs sticky

bits, and external memory 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.

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 the PCIe MMRs 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.

7.4.4 Local Reset

The local reset can be used to reset a particular CorePac without resetting any other chip components.

Local reset is initiated by the following (for more details see the Phase Locked Loop (PLL) for KeyStone Devices User

Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73:

•LRESET

• Watchdog timer should cause one of the below based on the setting of the CORESEL[2:0] and RSTCFG

on page 173:

–Local reset

–NMI

–NMI followed by a time delay and then a local reset for the CorePac selected

–Hard Reset by requesting reset via PLLCTL

• LPSC MMRs (memory-mapped registers)

7.4.5 Reset Priority

If any of the above reset sources occur simultaneously, the PLLCTL processes only the highest priority reset request.

The reset request priorities are as follows (high to low):

•Power-on reset

• Hard/soft reset

7.4.6 Reset Controller Register

The reset controller register are part of the PLLCTL MMRs. All C6671 device-specific MMRs are covered in Section

7.5.3 ‘‘Main PLL Control Register’’ on page 145. For more details on these registers and how to program them, see

7.5 Main PLL and PLL Controller

This section provides a description of the Main PLL and the PLL Controller. For details on the operation of the PLL

Controller module, see the Phase Locked Loop (PLL) for KeyStone Devices User Guide in ‘‘Related Documentation

from Texas Instruments’’ on page 73.

The Main PLL is controlled by the standard PLL Controller. The PLL controller manages the clock ratios, alignment,

and gating for the system clocks to the device. Figure 7-7 shows a block diagram of the main PLL and the PLL

Controller.

Note—The Main PLL Controller registers can be accessed by any master in the device. The PLLM[5:0] bits

of the multiplier are controlled by the PLLM register inside the PLL controller and PLLM[12:6] bits are

controlled by the chip-level MAINPLLCTL0 register. The Output Divide and Bypass logic of the PLL are

controlled by fields in the SECCTL register in the PLL controller. Only PLLDIV2, PLLDIV5, and PLLDIV8

are programmable on the C6671 device. See the Phase Locked Loop (PLL) for KeyStone Devices User Guide

in ‘‘Related Documentation from Texas Instruments’’ on page 73 for more details on how to program the

PLL controller.

The multiplication and division ratios within the PLL and the post-division for each of the chip-level clocks are

determined by a combination of this PLL and the PLL Controller. 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.

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 73 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/SRIO/HyperLink/PCIe Clock Input Electrical Data/Timing’’.

CAUTION—The PLL controller module as described in the see the Phase Locked Loop (PLL) for KeyStone

Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73 includes a superset of

features, some of which are not supported on the TMS320C6671 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 and the network coprocessor (PASS)) requires a PLL controller to manage the various clock divisions, gating,

and synchronization. The Main 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, HyperLink, CPU/2 TeraNet, DDR EMIF and CPU/2

EDMA.

•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.H

•SYSCLK6: 1/64-rate clock. 1/64 rate clock (emif_ptv) used to clock the PVT compensated buffers for DDR3

EMIF.

SPRS756D—April 2013

Fixed and Floating-Point Digital Signal Processor

TMS320C6671

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.

•SYSCLK10: 1/3-rate clock for SRIO only.

•SYSCLK11: 1/6-rate clock for PSC only.

Only SYSCLK2, SYSCLK5, and SYSCLK8 are programmable on theTMS320C6671 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.

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 elapsed.

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) to when to

when the PLL Controller can be switched to PLL mode. The Main PLL lock time is given in Table 7-13.

7.5.2.8 Reset Configuration Register (RSTCFG)

This register is used to configure the type of reset initiated by RESET, watchdog timer and the PLL Controller’s

RSTCTRL Register; i.e., a hard reset or a soft reset. By default, these resets will be hard resets. The Reset

Configuration Register (RSTCFG) is shown in Figure 7-15 and described in Table 7-22.

values of PLL multiplier, divide ratios and other settings. Along with setting module specific bit in RSISO, the

corresponding MDCTLx[12] bit also needs to be set in PSC to reset isolate a particular module. For more

Figure 7-16 and described in Table 7-23.

Note—The boot ROM code will enable the reset isolation for both SRIO and SmartReflex modules during

boot with the Reset Isolation Register. It is up to the user application to disable.

7.5.3 Main PLL Control Register

The Main PLL uses two chip-level registers (MAINPLLCTL0 and MAINPLLCTL1) along with the PLL Controller

for its configuration. 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 valid configurable values into the

MAINPLLCTL0 and MAINPLLCTL1 registers see Section 2.5.4 ‘‘PLL Boot Configuration Settings’’ on page 41. See

section 3.3.4 ‘‘Kicker Mechanism (KICK0 and KICK1) Register’’ on page 81 for the address location of the registers

and locking and unlocking sequences for accessing the registers. The registers are reset on POR only.

7.6 DD3 PLL

The DDR3 PLL generates interface clocks for the DDR3 memory controller. 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 DDR3 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 73. 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).

Figure 7-21 shows the DDR3 PLL.

As shown in Figure 7-21, the output of DDR3 PLL (PLLOUT) is divided by 2 and directly fed to the DDR3 memory

controller. 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 129. 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.

7.7 PASS PLL

The PASS PLL generates interface clocks for the Network Coprocessor. Using the PACLKSEL pin the user can select

the input source of PASS PLL as either the output of CORECLK clock reference sources or the PASSCLK clock

reference sources. When coming out of power-on reset, PASS PLL comes out in a bypass mode and needs to be

programmed to a valid frequency before being enabled and used.

PASS PLL power is supplied via the PASS PLL power-supply pin (AVDDA3). An external EMI filter circuit must be

7.8 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 are 3 EDMA Channel Controllers on the C6671 DSP, EDMA3CC0, EDMA3CC1, and EDMA3CC2.

• EDMA3CC0 has two transfer controllers: EDMA3TC1 and EDMA3TC2.

• EDMA3CC1 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.

• EDMA3CC2 has four transfer controllers: EDMA3TC0, EDMA3TC1, EDMA3TC2, and EDMA3TC3.

In the context of this document, EDMA3TCx associated with EDMA3CCy, and is referred to as EDMA3CCy TCx.

Each of the transfer controllers has a direct connection to the switch fabric. Section 4.2 ‘‘Switch Fabric Connections’’

lists the peripherals that can be accessed by the transfer controllers.

EDMA3CC0 is optimized to be used for transfers to/from/within the MSMC and DDR-3 Subsytems. The others are

to be used for the remaining traffic.

Each EDMA3 Channel Controller includes the following features:

• Fully orthogonal transfer description

–Three 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

• 128 PaRAM entries for EDMA3CC0, 512 each for EDMA3CC1 and EDMA3CC2

–Used to define transfer context for channels

–Each PaRAM entry can be used as a DMA entry, QDMA entry, or link entry

• 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2

–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 per EDMA 3 Channel Controller

–Used for software-driven transfers

–Triggered upon writing to a single PaRAM set entry

• Two transfer controllers and two event queues with programmable system-level priority for EDMA3CC0, four

transfer controllers and four event queues with programmable system-level priority per channel controller for

EDMA3CC1 and EDMA3CC2

• 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

7.8.1 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 C6671 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

Memory Access 3 (EDMA3) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’

on page 73.

For the range of memory addresses that include EDMA3 channel controller (EDMA3CC) control registers and

EDMA3 transfer controller (EDMA3TC) control register see Section Table 2-2‘‘Memory Map Summary’’ on

page 21. For memory offsets and other details on EDMA3CC and EDMA3TC control registers entries, see the

Enhanced Direct Memory Access 3 (EDMA3) for KeyStone Devices User Guide in ‘‘Related Documentation from

Texas Instruments’’ on page 73.

7.8.2 EDMA3 Channel Controller Configuration

Table 7-33 provides the configuration for each of the EDMA3 channel controllers present on the device.

7.8.3 EDMA3 Transfer Controller Configuration

Each transfer controller on a device is designed differently based on considerations like performance requirements,

system topology (like main TeraNet bus width, external memory bus width), etc. The parameters that determine the

transfer controller configurations are:

•FIFOSIZE: Determines the size in bytes for the data FIFO that is the temporary buffer for the in-flight data.

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 fixed by the design of the device.

Table 7-34 provides the configuration for each of the EDMA3 transfer controllers present on the device.

7.8.4 EDMA3 Channel Synchronization Events

The EDMA3 supports up to 16 DMA channels for EDMA3CC0, 64 each for EDMA3CC1 and EDMA3CC2 that can

be used to service system peripherals and to move data between system memories. 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 EDMA EDMA3CC DMA channels. On the C6671, the association

of each synchronization event and DMA channel is fixed and cannot be reprogrammed.

7.9 Interrupts

7.9.1 Interrupt Sources and Interrupt Controller

The CPU interrupts on the C6671 device are configured through the C66x CorePac Interrupt Controller. 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 chip interrupt controller (CIC) blocks. This is clocked using CPU/6.

The event controllers consist of simple combination logic to provide additional events to the C66x CorePac, plus the

EDMA3CC and CIC0 provide 17 additional events as well as 8 broadcast events to the C66x CorePac, CIC2 provides

26 and 24 additional events to EDMA3CC1 and EDMA3CC2 respectively, and CIC3 provides 8 and 32 additional

events to EDMA3CC0 and HyperLink respectively.

There are a large number of events at 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. 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 73.

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.
