SMQ320LC31 军用数字信号处理器

The SMJ320C31, SMJ320LC31, and SMQ320LC31 digital signal processors (DSPs) are 32-bit, floating-point processors manufactured in 0.6-µm triple-level-metal CMOS technology. The devices are part of the SMJ320C3x generation of DSPs from Texas Instruments.

The SMJ320C3x internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 60 MFLOPS. The SMJ320C3x 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 SMJ320C3x can perform parallel multiply and ALU operations on integer or floating-point data in a single cycle
