TMS320C5420PGEA200

定点数字信号处理器 FIXED-POINT DIGITAL SIGNAL PROCESSOR

description

The TMS320VC5420 fixed-point digital signal processor DSP is a dual CPU device capable of up to 200-MIPS performance. The 5420 consists of two independent 54x subsystems capable of core-to-core communications.

Each subsystem CPU is based on an advanced, modified Harvard architecture that has one program memory bus and three data memory buses. The processor also provides an arithmetic logic unit ALU that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals.
