description
The TMS320C62x DSPs (including the TMS320C6211/C6211B devices) compose one of the fixed-point DSP
families in the TMS320C6000 DSP platform. The TMS320C6211 (C6211) and TMS320C6211B (C6211B)
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 1333 million instructions per second (MIPS) at a clock rate of 167 MHz, the
C6211/C6211B device offers cost-effective solutions to high-performance DSP programming challenges. The
C6211/C6211B 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 six arithmetic logic units (ALUs) for a high
degree of parallelism and two 16-bit multipliers for a 32-bit result. The C6211/C6211B can produce two
multiply-accumulates (MACs) per cycle for a total of 333 million MACs per second (MMACS). The
C6211/C6211B DSP also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals.
The C6211/C6211B 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 C6211/C6211B 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 C62x 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.
Another key feature of the C62x 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
C62x 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 C62x 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 C6211/11B, 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 TMS320C6000 DSP Enhanced Direct Memory Access (EDMA) Controller Reference Guide (literature

interrupt sources and interrupt selector
The C62x 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 with appropriate disclaimers
describing their limitations and intended uses. Experimental devices (TMX) may not be representative of a
final product and Texas Instruments reserves the right to change or discontinue these products without notice.
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, -167 is 167 MHz).
Figure 4 provides a legend for reading the complete device name for any TMS3206000 DSP family member.

clock PLL
All of the internal C62x 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 C62x 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.
D. EMI filter manufacturer: TDK part number ACF451832-333, 223, 153, 103. Panasonic part number EXCCET103U.

triggering, wake-up, and effects
The power-down modes and their wake-up methods are programmed by setting the PWRD field (bits 15−10)
of the control status register (CSR). The PWRD field of the CSR is shown in Figure 8 and described in Table 20.
When writing to the CSR, all bits of the PWRD field should be set at the same time. Logic 0 should be used when
“writing” to the reserved bit (bit 15) of the PWRD field. The CSR is discussed in detail in the TMS320C6000 CPU
and Instruction Set Reference Guide (literature number SPRU189).

Figure 8. PWRD Field of the CSR Register
A delay of up to nine clock cycles may occur after the instruction that sets the PWRD bits in the CSR before the
PD mode takes effect. As best practice, NOPs should be padded after the PWRD bits are set in the CSR to account
for this delay.
If PD1 mode is terminated by a non-enabled interrupt, the program execution returns to the instruction where
PD1 took effect. If PD1 mode is terminated by an enabled interrupt, the interrupt service routine with be executed
first, then the program execution returns to the instruction where PD1 took effect. In the case with an enabled
interrupt, the GIE bit in the CSR and the NMIE bit in the interrupt enable register (IER) must also be set in order
for the interrupt service routine to execute; otherwise, execution returns to the instruction where PD1 took effect
upon PD1 mode termination by an enabled interrupt.
PD2 and PD3 modes can only be aborted by device reset. Table 20 summarizes all the power-down modes.

Input clock to the PLL stops generating clocks. All register and

the last state when the PLL clock is turned off. Following reset, the
PLL needs time to re-lock, just as it does following power-up.
Wake-up from PD3 takes longer than wake-up from PD2 because
the PLL needs to be re-locked, just as it does following power-up.

†When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or
peripherals with an external clock source, output signals may transition in response to stimulus on the inputs. Under these conditions,
peripherals will not operate according to specifications.

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.

IEEE 1149.1 JTAG compatibility statement
The TMS320C6211/C6211B DSP requires that both TRST and RESET resets be asserted upon power up to
be properly initialized. While RESET initializes the DSP core, TRST initializes the DSP’s emulation logic. Both
resets are required for proper operation.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the
DSP to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface
and DSP’s emulation logic in the reset state.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the DSP or exercise
the DSP’s boundary scan functionality.
For maximum reliability, the TMS320C6211/C6211B DSP includes an internal pulldown (IPD) on the TRST pin
to ensure that TRST will always be asserted upon power up and the DSP’s internal emulation logic will always
be properly initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG controllers
may not drive TRST high but expect the use of an external pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the DSP after powerup and externally drive
TRST high before attempting any emulation or boundary scan operations. Following the release of RESET, the
low-to-high transition of TRST must be “seen” to latch the state of EMU1 and EMU0. The EMU[1:0] pins
configure the device for either Boundary Scan mode or Emulation mode. For more detailed information, see
the terminal functions section of this data sheet.
EMIF device speed
TI recommends utilizing the input/output buffer information specification (IBIS) models to analyze all AC timings.
To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models
for Timing Analysis application report (literature number SPRA839).

bootmode
The C62x device resets using the active-low signal RESET signal (for the C6211/C6211B device, the RESET
signal is the same as the internal reset signal). While RESET is low, the internal reset is also asserted and the
device is held in reset and is initialized to the prescribed reset state. Refer to reset timing for reset timing
characteristics and states of device pins during reset. The release of the internal reset signal (see the Reset
Phase 3 discussion in the Reset Timing section of this data sheet) starts the processor running with the
prescribed device configuration and boot mode.
The C6211/C6211B has three types of boot modes:
DHost boot
If host boot is selected, upon release of internal reset, the CPU is internally “stalled” while the remainder of
the device is released. During this period, an external host can initialize the CPU’s memory space as
necessary through the host interface, including internal configuration registers, such as those that control
the EMIF or other peripherals. Once the host is finished with all necessary initialization, it must set the
DSPINT bit in the HPIC register to complete the boot process. This transition causes the boot configuration
logic to bring the CPU out of the “stalled” state. The CPU then begins execution from address 0. The DSPINT
condition is not latched by the CPU, because it occurs while the CPU is still internally “stalled”. Also, DSPINT
brings the CPU out of the “stalled” state only if the host boot process is selected. All memory may be written
to and read by the host. This allows for the host to verify what it sends to the DSP if required. After the CPU is
out of the “stalled” state, the CPU needs to clear the DSPINT, otherwise, no more DSPINTs can be received.
DEmulation boot
Emulation boot mode is a variation of host boot. In this mode, it is not necessary for a host to load code or to
set DSPINT to release the CPU from the “stalled” state. Instead, the emulator will set DSPINT if it has not
been previously set so that the CPU can begin executing code from address 0. Prior to beginning execution,
the emulator sets a breakpoint at address 0. This prevents the execution of invalid code by halting the CPU
prior to executing the first instruction. Emulation boot is a good tool in the debug phase of development.
DEMIF boot (using default ROM timings)
Upon the release of internal reset, the 1K-Byte ROM code located in the beginning of CE1 is copied to
address 0 by the EDMA using the default ROM timings, while the CPU is internally “stalled”. The data should
be stored in the endian format that the system is using. The boot process also lets you choose the width of
the ROM. In this case, the EMIF automatically assembles consecutive 8-bit bytes or 16-bit half-words to
form the 32-bit instruction words to be copied. The transfer is automatically done by the EDMA as a
single-frame block transfer from the ROM to address 0. After completion of the block transfer, the CPU is
released from the “stalled” state and start running from address 0.

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:
DIn typical boards with the C6211B 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)].
DIn some boards with the C6211BGFNA 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 21 and Figure 12).
Figure 12 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.

enough (e.g., pulse width = 2E) to ensure setup and hold time is met.

‡P = 1/CPU clock frequency in ns. For example, when running parts at 167 MHz, use P = 6 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 83 Mbps for 167 MHz CPU clock or 75 Mbps for 150 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 167 MHz (P = 6 ns), use 30 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 =
