Texas Instruments

The TMS320C64x™ DSPs (including the SMJ320C6414, SMJ320C6415, and SMJ320C6416 devices) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320C64x™ (C64x™†) device is based on the second-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™) developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and multifunctional applications. The C64x™ is a code-compatible member of the C6000™ DSP platform.
With performance of up to 5760 million instructions per second (MIPS) at a clock rate of 720 MHz, the C64x devices offer cost-effective solutions to high-performance DSP programming challenges. The C64x DSPs possess the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x™ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs)— with VelociTI.2™ extensions. The VelociTI.2™ extensions in the eight functional units include new instructions to accelerate the performance in key applications and extend the parallelism of the VelociTI™ architecture. The C64x can produce four 32-bit multiply-accumulates (MACs) per cycle for a total of 2400 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4800 MMACS. The C64x DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000™ DSP platform devices.
