description
The TMP/SMJ320C31KGDB and SMJ320LC31KGDB digital signal processors (DSPs) known good dies
(KGDs) are high-performance, 32-bit floating-point processors manufactured in 0.72-
m, double-level metal
CMOS technology.
The TMP/SMJ320C31KGDB and SMJ320LC31KGDB internal busing and special digital signal processing
instruction set have the speed and flexibility to execute up to 40 million floating-point operations per second
(MFLOPS). The devices optimize 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.
The devices can perform parallel multiply and ALU operations on integer or floating-point data in a single cycle.
Each processor also possesses a general-purpose register file, a program cache, dedicated ARAUs, internal
dual-access memories, one DMA channel supporting concurrent I / O, and a short machine-cycle time. High
performance and ease of use are results of these features.
