SM320C32ĆEP
DIGITAL SIGNAL PROCESSOR
SGUS038 − AUGUST 2002
description
The SM320C32-EP is a member of the 320C3x generation of digital signal processors from Texas Instruments.
The SM320C32-EP is an enhanced 32-bit floating-point processor manufactured in 0.7-µm triple-level-metal
CMOS technology. The enhancements to the 320C3x architecture include a variable-width external-memory
interface, faster instruction cycle time, power-down modes, two-channel DMA coprocessor with configurable
priorities, flexible bootloader, relocatable interrupt-vector table, and edge- or level-triggered interrupts.
The internal busing and special digital signal processing instruction set of the SM320C32-EP have the speed
and flexibility to execute up to 50 million floating-point operations per second (MFLOPS). The SM320C32-EP
optimizes speed by implementing functions in hardware that other processors implement through software or
microcode. This hardware-intensive approach provides performance previously unavailable on a single chip.
For additional information when designing for cold temperature operation, please see Texas Instruments
application report 320C3x, 320C4x and 320MCM42x Power-up Sensitivity at Cold Temperature, literature
number SGUA001.
