2.2.1
(DSP Core) Description
C64x+ Central Processing Unit (CPU) consists eight functional units, register files, data paths shown Figure 2-2. general-purpose register files each contain 32-bit registers total registers. general-purpose registers used data data address pointers. data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40-bit data, 64-bit data. Values larger than bits, such 40-bit-long 64-bit-long values stored register pairs, with LSBs data placed even register remaining MSBs next upper register (which always odd-numbered register). eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, .S2) each capable executing instruction every clock cycle. functional units perform multiply operations. units perform general arithmetic, logical, branch functions. units primarily load data from memory register file store results from register file into memory. C64x+ extends performance C64x core through enhancements features. Each C64x+ unit perform following each clock cycle: multiply, multiply, multiplies, multiplies, multiplies with add/subtract capabilities, four multiplies, four multiplies with operations, four multiplies with add/subtract capabilities (including complex multiply). There also support Galois field multiplication 8-bit 32-bit data. Many communications algorithms such FFTs modems require complex multiplication. complex multiply (CMPY) instruction takes 16-bit inputs produces 32-bit real 32-bit imaginary output. There also complex multiplies with rounding capability that produces 32-bit packed output that contain 16-bit real 16-bit imaginary values. multiply instructions provide extended precision necessary audio other high-precision algorithms variety signed unsigned 32-bit data types. (Arithmetic Logic Unit) incorporates ability parallel add/subtract operations pair common inputs. Versions this instruction exist work 32-bit data pairs 16-bit data performing dual 16-bit subtracts parallel. There also saturated forms these instructions. C64x+ core enhances unit several ways. C64x core, dual 16-bit MIN2 MAX2 comparisons were only available units. C64x+ core they also available unit which increases performance algorithms that searching sorting. Finally, increase data packing unpacking throughput, unit allows sustained high performance quad 8-bit/16-bit dual 16-bit instructions. Unpack instructions prepare 8-bit data parallel 16-bit operations. Pack instructions return parallel results output precision including saturation support. Other features include: SPLOOP small instruction buffer that aids creation software pipelining loops where multiple iterations loop executed parallel. SPLOOP buffer reduces code size associated with software pipelining. Furthermore, loops SPLOOP buffer fully interruptible. Compact Instructions native instruction size C6000 devices bits. Many common instructions such MPY, AND, ADD, expressed bits C64x+ compiler restrict code certain registers register file. This compression performed code generation tools.

Instruction Enhancement noted above, there instructions such 32-bit multiplications, complex multiplications, packing, sorting, manipulation, 32-bit Galois field multiplication. Exceptions Handling Intended programmer isolating bugs. C64x+ able detect respond exceptions, both from internally detected sources (such illegal op-codes) from system events (such watchdog time expiration). Privilege Defines user supervisor modes operation, allowing operating system give basic level protection sensitive resources. Local memory divided into multiple pages, each with read, write, execute permissions.

designate stages product development cycle, assigns prefixes part numbers devices support tools. Each commercial family member three prefixes: TMX, TMP, (e.g., TMX320C6424ZWTQ6). Texas Instruments recommends three possible prefix designators support tools: TMDX TMDS. These prefixes represent evolutionary stages product development from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS). Device development evolutionary flow: Experimental device that necessarily representative final device's electrical specifications. Final silicon that conforms device's electrical specifications completed quality reliability verification. Fully-qualified production device.
Support tool development evolutionary flow: TMDX TMDS Development-support product that completed Texas Instruments internal qualification testing. Fully qualified development-support product.

Predictions show that prototype devices (TMX TMP) have greater failure rate than standard production devices. Texas Instruments recommends that these devices used production system because their expected end-use failure rate still undefined. Only qualified production devices used. device nomenclature also includes suffix with device family name. This suffix indicates package type (for example, ZWT), temperature range (for example, "Blank" commercial temperature range), device speed range megahertz (for example, "Blank" default [600-MHz]).

VDD3P3V_PWDN register System Module (see Figure 3-1) used selectively power down unused 3.3-V pins. independent control, 3.3-V I/Os separated into functional groups-most which named according multiplexing groups (see Table 3-2). these groups, only buffers needed Host/EMIFA Boot Power-Up Operations powered default (CLKOUT Block, EMIFA Block, Host Block, Data Block, GPIO Block). Note: save power, other buffers powered down default. Before using these pins, user must program VDD3P3V_PWDN register power corresponding buffers. list multiplexed pins device group each belongs Section 3.7.3.1, Multiplexed Pins C6424. Note: VDD3P3V_PWDN register only controls power buffers. Power Sleep Controller (PSC) determines clock/power state peripheral.
