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 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 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.

Each TMS320™ DSP member has one of three prefixes: TMX, TMP, or TMS, and each SMJ320™ DSP member has one of three prefixes: SMX, SM, or SMJ. 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). This development flow is defined below. Device development evolutionary flow: SMX 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 SM/SMJ 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 as well as SM/SMJ devices and TMDS development support tools have been characterized fully, and the quality and reliability of the device has 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, GNM) and temperature range (for example, M). Figure 4 provides a legend for reading the complete device name for many TMS320™ DSP family members. TMS320 is a trademark of Texas Instruments.

This source clock either drives the PLL, which generates the internal CPU clock, or bypasses the PLL to become the CPU clock. To use the PLL to generate the CPU clock, the filter circuit shown in Figure 5 must be properly designed. Note that for C6201, the EMI filter must be powered by the I/O voltage (3.3 V). To configure the C62x™ PLL clock for proper operation, see Figure 5 and Table 2. To minimize the clock jitter, a single clean power supply should power both the C62x™ DSP device and the external clock oscillator circuit. The minimum CLKIN rise and fall times should also be observed. See the input and output clocks section for input clock timing requirements.

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. For CLKMODE x4, values for C1, C2, and R1 are fixed and apply to all valid frequency ranges of CLKIN and CLKOUT. B. For CLKMODE x1, the PLL is bypassed and all six external PLL components can be removed. For this case, the PLLV terminal has to be connected to a clean supply and the PLLG and PLLF terminals should be tied together. C. Due to overlap of frequency ranges when choosing the PLLFREQ, more than one frequency range can contain the CLKOUT1 frequency. Choose the lowest frequency range that includes the desired frequency. For example, for CLKOUT1 = 133 MHz, a PLLFREQ value of 000b should be used. For CLKOUT1 = 200 MHz, PLLFREQ should be set to 001b. PLLFREQ values other than 000b, 001b, and 010b are reserved. D. The 3.3-V supply for the EMI filter (and PLLV) must be from the same 3.3-V power plane supplying the I/O voltage, DVDD. E. EMI filter manufacturer TDK part number ACF451832-153-T Figure 5.

For example, if the typical lock time is specified as 100 μs, the maximum value may be as long as 250 μs. 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, an external clock pulse 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.

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 DMA auxiliary channel, and HRDY remains high until the DMA auxiliary channel 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.

Addendum-Page 1 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
