The TMS320C67x DSPs are the floating-point DSP family in the TMS320C6000TM DSP platform. The TMS320C6701 ('C6701) device is based on the high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an excellent choice for multichannel and multifunction applications. With performance to 1 giga floating-point operations per second (GFLOPS) at a clock rate of 167 MHz, the 'C6701 offers cost-effective solutions to high-performance DSP programming challenges. The 'C6701 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 four floating-/fixed-point ALUs, two fixed-point ALUs, and two floating-/fixed-point multipliers. The 'C6701 can produce two multiply-accumulates (MACs) per cycle for a total of 334 million MACs per second (MMACS). The 'C6701 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The 'C6701 includes a large bank of on-chip memory and has a powerful and diverse set of peripherals. Program memory consists 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 host-port interface (HPI), and a glueless external memory interface (EMIF) capable of interfacing to SDRAM or SBSRAM and asynchronous peripherals. The 'C6701 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a WindowsTM debugger interface for visibility into source code execution.
