SM320LC31-EP 增强型产品数字信号处理器

The SM320LC31-EP digital signal processor (DSP) is a 32-bit, floating-point processor manufactured in 0.6-um triple-level-metal CMOS technology. The device is part of the SMJ320C3x generation of DSPs from Texas Instruments.

The SM320LC31-EP internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 60 MFLOPS. The SM320LC31-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.

The SM320LC31-EP 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
