TMS320C6711, TMS320C6711B
FLOATING-POINT DIGITAL SIGNAL PROCESSORS
SPRS088B – FEBRUARY 1999 – REVISED SEPTEMBER 2001
description
The TMS320C67x DSPs (including the TMS320C6711/C6711B devices) compose the floating-point DSP
family in the TMS320C6000 DSP platform. The TMS320C6711 (C6711) and TMS320C6711B (C6711B)
devices are based on the high-performance, advanced VelociTI very-long-instruction-word (VLIW)
architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and
multifunction applications.
With performance of up to 900 million floating-point operations per second (MFLOPS) at a clock rate of
150 MHz, the C6711/C6711B device also offers cost-effective solutions to high-performance DSP
programming challenges. The C6711/C6711B DSP possesses the operational flexibility of high-speed
controllers and the numerical capability of array processors. This processor has 32 general-purpose registers
of 32-bit word length and eight highly independent functional units. The eight functional units provide four
floating-/fixed-point ALUs, two fixed-point ALUs, and two floating-/fixed-point multipliers. The C6711/C6711B
can produce two MACs per cycle for a total of 300 MMACS. The C6711/C6711B DSP also has
application-specific hardware logic, on-chip memory, and additional on-chip peripherals.
The C6711/C6711B uses a two-level cache-based architecture and has a powerful and diverse set of
peripherals. The Level 1 program cache (L1P) is a 32-Kbit direct mapped cache and the Level 1 data cache
(L1D) is a 32-Kbit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 512-Kbit memory
space that is shared between program and data space. L2 memory can be configured as mapped memory,
cache, or combinations of the two.The peripheral set includes two multichannel buffered serial ports (McBSPs),
two general-purpose timers, a host-port interface (HPI), and a glueless external memory interface (EMIF)
capable of interfacing to SDRAM, SBSRAM and asynchronous peripherals.
The C6711/C6711B has a complete set of development tools which includes: a new C compiler, an assembly
optimizer to simplify programming and scheduling, and a Windows debugger interface for visibility into source
code execution.

CPU (DSP core) description
The CPU fetches VelociTI advanced very-long instruction words (VLIW) (256 bits wide) to supply up to eight
32-bit instructions to the eight functional units during every clock cycle. The VelociTI VLIW architecture
features controls by which all eight units do not have to be supplied with instructions if they are not ready to
execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute
packet as the previous instruction, or whether it should be executed in the following clock as a part of the next
execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The
variable-length execute packets are a key memory-saving feature, distinguishing the C67x CPU from other
VLIW architectures.
The CPU features two sets of functional units. Each set contains four units and a register file. One set contains
functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files
each contain 16 32-bit registers for a total of 32 general-purpose registers. The two sets of functional units, along
with two register files, compose sides A and B of the CPU (see the functional block and CPU diagram and
Figure 1). The four functional units on each side of the CPU can freely share the 16 registers belonging to that
side. Additionally, each side features a single data bus connected to all the registers on the other side, by which
the two sets of functional units can access data from the register files on the opposite side. While register access
by functional units on the same side of the CPU as the register file can service all the units in a single clock cycle,
register access using the register file across the CPU supports one read and one write per cycle.
The C67x CPU executes all C62x instructions. In addition to C62x fixed-point instructions, the six out of eight
functional units (.L1, .S1, .M1, .M2, .S2, and .L2) also execute floating-point instructions. The remaining two
functional units (.D1 and .D2) also execute the new LDDW instruction which loads 64 bits per CPU side for a
total of 128 bits per cycle.
Another key feature of the C67x CPU is the load/store architecture, where all instructions operate on registers
(as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data
transfers between the register files and the memory. The data address driven by the .D units allows data
addresses generated from one register file to be used to load or store data to or from the other register file. The
C67x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing modes
with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 32 registers. Some
registers, however, are singled out to support specific addressing or to hold the condition for conditional
instructions (if the condition is not automatically “true”). The two .M functional units are dedicated for multiplies.
The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results
available every clock cycle.
The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory.
The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least
significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous
execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain,
effectively placing the instructions that follow it in the next execute packet. If an execute packet crosses the
fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of
the current fetch packet is padded with NOP instructions. The number of execute packets within a fetch packet
can vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one
per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch
packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units
for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit
registers, they can be subsequently moved to memory as bytes or half-words as well. All load and store
instructions are byte-, half-word, or word-addressable.

EDMA channel synchronization events
The C67x EDMA supports up to 16 EDMA channels. Four of the sixteen channels (channels 8–11) are reserved
for EDMA chaining, leaving 12 EDMA channels available to service peripheral devices. Table 15 lists the source
of synchronization events associated with each of the programmable EDMA channels. For the C6711/11B, the
association of an event to a channel is fixed; each of the EDMA channels has one specific event associated
with it. For more detailed information on the EDMA module, associated channels, and event-transfer chaining,
see the EDMA Controller chapter of the TMS320C6000 Peripherals Reference Guide (literature number
SPRU190).

interrupt sources and interrupt selector
The C67x DSP core supports 16 prioritized interrupts, which are listed in Table 16. The highest-priority interrupt
is INT_00 (dedicated to RESET) while the lowest-priority interrupt is INT_15. The first four interrupts
(INT_00–INT_03) are non-maskable and fixed. The remaining interrupts (INT_04–INT_15) are maskable and
default to the interrupt source specified in Table 16. The interrupt source for interrupts 4–15 can be programmed
by modifying the selector value (binary value) in the corresponding fields of the Interrupt Selector Control
registers: MUXH (address 0x019C0000) and MUXL (address 0x019C0004).

device and development-support tool nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
TMS320 DSP devices and support tools. Each TMS320 DSP commercial family member has one of three
prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for
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 against 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,GFN), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -150 is 150 MHz).
Figure 4 provides a legend for reading the complete device name for any TMS3206000 DSP family member.

documentation support
Extensive documentation supports all TMS320 DSP family generations of devices from product
announcement through applications development. The types of documentation available include: data sheets,
such as this document, with design specifications; complete user’s reference guides for all devices and tools;
technical briefs; development-support tools; on-line help; and hardware and software applications. The
following is a brief, descriptive list of support documentation specific to the C6000 DSP devices:
The TMS320C6000 CPU and Instruction Set Reference Guide (literature number SPRU189) describes the
C6000 CPU (DSP core) architecture, instruction set, pipeline, and associated interrupts.
The TMS320C6000 Peripherals Reference Guide (literature number SPRU190) describes the functionality of
the peripherals available on the C6000 DSP platform of devices, such as the external memory interface
(EMIF), host-port interface (HPI), multichannel buffered serial ports (McBSPs), direct-memory-access (DMA),
enhanced direct-memory-access (EDMA) controller, expansion bus (XB), clocking and phase-locked loop
(PLL); and power-down modes. This guide also includes information on internal data and program memories.
The TMS320C6000 Technical Brief (literature number SPRU197) gives an introduction to the
TMS320C62x/TMS320C67x devices, associated development tools, and third-party support.
The tools support documentation is electronically available within the Code Composer Studio Integrated
Development Environment (IDE). For a complete listing of C6000 DSP latest documentation, visit the Texas

clock PLL
All of the internal C67x clocks are generated from a single source through the CLKIN pin. This source clock
either drives the PLL, which multiplies the source clock in frequency to generate the internal CPU clock, or
bypasses the PLL to become the internal CPU clock.
To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 5
shows the external PLL circuitry for either x1 (PLL bypass) or x4 PLL multiply modes. Figure 6 shows the
external PLL circuitry for a system with ONLY x1 (PLL bypass) mode.
To minimize the clock jitter, a single clean power supply should power both the C67x device and the external
clock oscillator circuit. Noise coupling into PLLF will directly impact PLL clock jitter. The minimum CLKIN rise
and fall times should also be observed. For the input clock timing requirements, see the input and output clocks
electricals section.
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock source
must meet the DSP requirements in this data sheet (see the electrical characteristics over recommended
ranges of suppy voltage and operating case temperature table and the input and output clocks electricals
section). Table 18 lists some examples of compatible CLKIN external clock sources:

NOTES: A. Keep the lead length and the number of vias between the PLLF pin, the PLLG pin, and R1, C1, and C2 to a minimum. In addition,
place all PLL external components (R1, C1, C2, C3, C4, and the EMI Filter) as close to the C6000 device as possible. 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 the ones shown.
B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (R1, C1, C2, C3, C4,
and the EMI filter).
C. The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DVDD.

power-supply sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time if the other
supply is below the proper operating voltage.
system-level design considerations
System-level design considerations, such as bus contention, may require supply sequencing to be
implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered
down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the
output buffers are powered up, thus, preventing bus contention with other chips on the board.
power-supply design considerations
For systems using the C6000 DSP platform of devices, the core supply may be required to provide in excess
of 2 A per DSP until the I/O supply is powered up. This extra current condition is a result of uninitialized logic
within the DSP(s) and is corrected once the CPU sees an internal clock pulse. With the PLL enabled, as the
I/O supply is powered on, a clock pulse is produced stopping the extra current draw from the supply. With the
PLL disabled, as many as five external clock cycle pulses may be required to stop this extra current draw. A
normal current state returns once the I/O power supply is turned on and the CPU sees a clock pulse. Decreasing
the amount of time between the core supply power up and the I/O supply power up can minimize the effects
of this current draw.
A dual-power supply with simultaneous sequencing, such as available with TPS563xx controllers or PT69xx
plug-in power modules, can be used to eliminate the delay between core and I/O power up [see the Using the
TPS56300 to Power DSPs application report (literature number SLVA088)]. A Schottky diode can also be used
to tie the core rail to the I/O rail, effectively pulling up the I/O power supply to a level that can help initialize the
logic within the DSP.
Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize
inductance and resistance in the power delivery path. Additionally, when designing for high-performance
applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for
core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors.

timing parameters and board routing analysis
The timing parameter values specified in this data sheet do not include delays by board routings. As a good
board design practice, such delays must always be taken into account. Timing values may be adjusted by
increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification
(IBIS) models to analyze the timing characteristics correctly. If needed, external logic hardware such as buffers
may be used to compensate any timing differences. For example:
D In typical boards with the C6711B commercial temperature device, the routing delay improves the external
memory’s ability to meet the DSP’s EMIF data input hold time requirement [th(EKOH-EDV)].
D In some boards with the C6711BGFNA extended temperature device, the routing delay improves the
external memory’s ability to meet the DSP’s EMIF data input hold time requirement [th(EKOH-EDV)]. In
addition, it may be necessary to add an extra delay to the input clock of the external memory to robustly
meet the DSP’s data input hold time requirement. If the extra delay approach is used, memory bus
frequency adjustments may be needed to ensure the DPS’s input setup time requirement [tsu(EDV-EKOH)]
is still maintained.
For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and
from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin,
but also tends to improve the input hold time margins (see Table 20 and Figure 10).
Figure 10 represents a general transfer between the DSP and an external device. The figure also represents
board route delays and how they are perceived by the DSP and the external device.

† HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
‡ P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.7 ns.
§ HCS enables HRDY, and HRDY is always low when HCS is high. The case where HRDY goes high when HCS falls indicates that HPI is busy
completing a previous HPID write or READ with autoincrement.
¶ This parameter is used during an HPID read. At the beginning of the first half-word transfer on the falling edge of HSTROBE, the HPI sends the
request to the EDMA internal address generation hardware, and HRDY remains high until the EDMA internal address generation hardware loads
the requested data into HPID.
# This parameter is used after the second half-word of an HPID write or autoincrement read. HRDY remains low if the access is not an HPID write
or autoincrement read. Reading or writing to HPIC or HPIA does not affect the HRDY signal.

† CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
‡ P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.7 ns.
§ The minimum CLKR/X period is twice the CPU cycle time (2P). This means that the maximum bit rate for communications between the McBSP
and other device is 75 Mbps for 150 MHz CPU clock or 50 Mbps for 100 MHz CPU clock; where the McBSP is either the master or the slave.
Care must be taken to ensure that the AC timings specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP
communications is 33 Mbps; therefore, the minimum CLKR/X clock cycle is either twice the CPU cycle time (2P), or 30 ns (33 MHz), whichever
value is larger. For example, when running parts at 150 MHz (P = 6.7 ns), use 33 ns as the minimum CLKR/X clock cycle (by setting the appropriate
CLKGDV ratio or external clock source). When running parts at 60 MHz (P = 16.67 ns), use 2P = 33 ns (30 MHz) as the minimum CLKR/X clock
cycle. The maximum bit rate for McBSP-to-McBSP communications applies when the serial port is a master of the clock and frame syncs (with
CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY =

† CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also inverted.
‡ Minimum delay times also represent minimum output hold times.
§ P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.7 ns.
¶ The minimum CLKR/X period is twice the CPU cycle time (2P). This means that the maximum bit rate for communications between the McBSP
and other device is 75 Mbps for 150 MHz CPU clock or 50 Mbps for 100 MHz CPU clock; where the McBSP is either the master or the slave.
Care must be taken to ensure that the AC timings specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP
communications is 33 Mbps; therefore, the minimum CLKR/X clock cycle is either twice the CPU cycle time (2P), or 30 ns (33 MHz), whichever
value is larger. For example, when running parts at 150 MHz (P = 6.7 ns), use 33 ns as the minimum CLKR/X clock cycle (by setting the appropriate
CLKGDV ratio or external clock source). When running parts at 60 MHz (P = 16.67 ns), use 2P = 33 ns (30 MHz) as the minimum CLKR/X clock
cycle. The maximum bit rate for McBSP-to-McBSP communications applies when the serial port is a master of the clock and frame syncs (with
CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY =
01b or 10b) and the other device the McBSP communicates to is a slave.
# C = H or L
S = sample rate generator input clock = 2P if CLKSM = 1 (P = 1/CPU clock frequency)
= sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see ¶ footnote above).
|| Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
If DXENA = 0, then D1 = D2 = 0
If DXENA = 1, then D1 = 2P, D2 = 4P

‡ Minimum delay times also represent minimum output hold times.
§ P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.7 ns.
¶ The minimum CLKR/X period is twice the CPU cycle time (2P). This means that the maximum bit rate for communications between the McBSP
and other device is 75 Mbps for 150 MHz CPU clock or 50 Mbps for 100 MHz CPU clock; where the McBSP is either the master or the slave.
Care must be taken to ensure that the AC timings specified in this data sheet are met. The maximum bit rate for McBSP-to-McBSP
communications is 33 Mbps; therefore, the minimum CLKR/X clock cycle is either twice the CPU cycle time (2P), or 30 ns (33 MHz), whichever
value is larger. For example, when running parts at 150 MHz (P = 6.7 ns), use 33 ns as the minimum CLKR/X clock cycle (by setting the appropriate
CLKGDV ratio or external clock source). When running parts at 60 MHz (P = 16.67 ns), use 2P = 33 ns (30 MHz) as the minimum CLKR/X clock
cycle. The maximum bit rate for McBSP-to-McBSP communications applies when the serial port is a master of the clock and frame syncs (with
CLKR connected to CLKX, FSR connected to FSX, CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY =
01b or 10b) and the other device the McBSP communicates to is a slave.
# C = H or L
S = sample rate generator input clock = 2P if CLKSM = 1 (P = 1/CPU clock frequency)
= sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see ¶ footnote above).
|| Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
If DXENA = 0, then D1 = D2 = 0
If DXENA = 1, then D1 = 2P, D2 = 4P

† P = 1/CPU clock frequency in ns. For example, when running parts at 150 MHz, use P = 6.7 ns.
‡ For all SPI slave modes, CLKG is programmed as 1/2 of the CPU clock by setting CLKSM = CLKGDV = 1.
§ S = Sample rate generator input clock = 2P if CLKSM = 1 (P = 1/CPU clock frequency)
= Sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
T = CLKX period = (1 + CLKGDV) * S
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
¶ FSRP = FSXP = 1. As a SPI master, FSX is inverted to provide active-low slave-enable output. As a slave, the active-low signal input on FSX
and FSR is inverted before being used internally.
CLKXM = FSXM = 1, CLKRM = FSRM = 0 for master McBSP
CLKXM = CLKRM = FSXM = FSRM = 0 for slave McBSP
# FSX should be low before the rising edge of clock to enable slave devices and then begin a SPI transfer at the rising edge of the master clock
(CLKX).
