description

The 320C67x DSPs are the floating-point DSP

family in the TMS320C6000? DSP platform. The

SM320C6701-EP and SM320C6701MECH-EP

(C6701) devices are based on the highperformance,

advanced VelociTI very-longinstruction-

word (VLIW) architecture developed

by Texas Instruments (TI), making this DSP an

excellent choice for multichannel and

multifunction applications. With performance of

up to 1 giga floating-point operations per second

(GFLOPS) at a clock rate of 167 MHz, the C6701

offers cost-effective solutions to highperformance

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-/fixedpoint

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 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 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 Windows? debugger interface for visibility into source code

execution.
