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.

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.

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).

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.

POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 25 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. 3.3V PLLV EMI Filter Internal to C6205 ED[31,27,23] (see Table 3) C3 10 mF C4 0.1 mF PLL CLKMODE0 (see Table 3) PLLMULT PLLCLK CLKIN CLKIN 1 LOOP FILTER C2 C1 CPU CLOCK PLLG PLLF 0 R1 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. Figure 5.

POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 27 SPRS106D – OCTOBER 1999 – REVISED FEBRUARY 2003 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. 28 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 SPRS106D – OCTOBER 1999 – REVISED FEBRUARY 2003 absolute maximum ratings over operating case temperature range (unless otherwise noted)† Supply voltage ranges: CVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . – 0.3 V to 2.3 V DVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 V to 4 V (PCI), VIOP (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to 5.5 V (PCI), VDDP (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 V to 4 V Input voltage ranges: (except PCI), VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 V to 4 V (PCI), VIP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to VIOP + 0.5 V Output voltage ranges: (except PCI), VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.3 V to 4 V (PCI), VOP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to VIOP + 0.5 V Operating case temperature range, TC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0_C to 90_C Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –65_C to 150_C † Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
