description
The TMS320C62x DSPs (including the TMS320C6205 device) compose the fixed-point DSP generation in
the TMS320C6000 DSP platform. The TMS320C6205 (C6205) device is based on the high-performance,
advanced VelociTI very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI),
making the C6205 an excellent choice for multichannel and multifunction applications.
With performance of up to 1600 million instructions per second (MIPS) at a clock rate of 200 MHz, the C6205
offers cost-effective solutions to high-performance DSP-programming challenges. The C6205 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 C6205 can produce two multiply-accumulates (MACs) per cycle for a total of
400 million MACs per second (MMACS). The C6205 DSP also has application-specific hardware logic, on-chip
memory, and additional on-chip peripherals.
The C6205 includes a large bank of on-chip memory and has a powerful and diverse set of peripherals. Program
memory consists of a 64K-byte block that is user-configurable as cache or memory-mapped program space.
Data memory consists of two 32K-byte blocks of RAM. The peripheral set includes two multichannel buffered
serial ports (McBSPs), two general-purpose timers, a peripheral component interconnect (PCI) module that
supports 33-MHz master/slave interface and 4-wire serial EEPROM interface, and a glueless external memory
interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals.
The C6205 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 and CPU (DSP Core) Block
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
256-bit wide fetch-packet boundary, 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.

memory map summary
Table 2 shows the memory map address ranges of the C6205 device. The C6205 device has the capability of
a MAP 0 or MAP 1 memory block configuration. The maps differ in that MAP 0 has external memory mapped
at address 0x0000 0000 and MAP 1 has internal memory mapped at address 0x0000 0000. These memory
block configurations are set up at reset by the boot configuration pins (generically called BOOTMODE[4:0]). For
the C6205 device, the BOOTMODE configuration is handled, at reset, by the expansion bus module (specifically
XD[4:0] pins). For more detailed information on the C6205 device settings, which include the device boot mode
configuration at reset and other device-specific configurations, see the Boot Configuration section and the Boot
Configuration Summary table of the TMS320C6000 Peripherals Reference Guide (literature number
SPRU190).

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, GHK), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -200 is 200 MHz).
Figure 4 provides a legend for reading the complete device name for any TMS320C6000 DSP family member.
For the C6205 device orderable part numbers (P/Ns), see the Texas Instruments web site on the Worldwide
web at http://www.ti.com URL, or contact the nearest TI field sales office, or authorized distributor.

documentation support
Extensive documentation supports all TMS320 DSP family 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 DSP core (CPU) 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 64-/32-/16-bit external memory
interfaces (EMIFs), 32-/16-bit host-port interfaces (HPIs), multichannel buffered serial ports (McBSPs), direct
memory access (DMA), enhanced direct-memory-access (EDMA) controller, expansion bus (XB), peripheral
component interconnect (PCI), 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 C62x/C67x
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 the latest C6000 DSP documentation, visit the
Texas Instruments web site on the Worldwide Web at http://www.ti.com uniform resource locator (URL).

SPRS106D – OCTOBER 1999 – REVISED FEBRUARY 2003
clock PLL
Most of the internal C6205 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,
Table 3, and Table 4 show 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 C6205 device and the external
clock oscillator circuit. Noise coupling into PLLF directly impacts 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.

NOTES: A. Keep the lead length and the number of vias between pin PLLF, pin PLLG, R1, C1, and C2 to a minimum. In addition, place all PLL
components (R1, C1, C2, C3, C4, and EMI Filter) as close to the C6000 DSP device as possible. Best performance is achieved
with the PLL components 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.
E. At power up, the PLL requires a falling edge of RESET to initialize the PLL engine. It may be necessary to toggle reset in order to
establish proper PLL operation.

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 that 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.

§ This parameter applies to CLKMODE x4, x6, x7, x8, x9, x10, and x11 only. The RESET signal is not connected internally to the Clock PLL circuit.
The PLL requires a minimum of 250 µs to stabilize following device power up or after PLL configuration has been changed. During that time,
RESET must be asserted to ensure proper device operation. See the clock PLL section for power up (specifically Figure 5, Note E) and for PLL
lock times (Table 4).

† CLKRP = CLKXP = FSRP = FSXP = 0. If the 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 200 MHz, use P = 5 ns.
§ The maximum bit rate for the C6205 devices is 100 Mbps or CPU/2 (the slower of the two). 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 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 200 MHz
(P = 5 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 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.
¶ The minimum CLKR/X pulse duration is either (P–1) or 4 ns, whichever is larger. For example, when running parts at 200 MHz (P = 5 ns), use
4 ns as the minimum CLKR/X pulse duration. When running parts at 100 MHz (P = 10 ns), use (P–1) = 9 ns as the minimum CLKR/X pulse

† CLKRP = CLKXP = FSRP = FSXP = 0. If the 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 200 MHz, use P = 5 ns.
¶ The maximum bit rate for the C6205 devices is 100 Mbps or CPU/2 (the slower of the two). 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 100 MHz; therefore, the minimum CLKR/X
clock cycle is either twice the CPU cycle time (2P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 200 MHz
(P = 5 ns), use 10 ns as the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running
parts at 100 MHz (P = 10 ns), use 2P = 20 ns (50 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 = P 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 100-MHz limit.
