Overview
The TMS320VC5420 is a fixed-point digital signal processor (DSP) from Texas Instruments, designed to deliver high-performance processing capabilities. This dual-core DSP consists of two independent 54x subsystems, each capable of core-to-core communications. The device is based on an advanced, modified Harvard architecture with one program memory bus and three data memory buses per core. It supports up to 200-MIPS performance and features a 40-bit Arithmetic Logic Unit (ALU), parallel multipliers, and various on-chip peripherals. The TMS320VC5420 is available in both commercial and industrial temperature ranges and is packaged in 144-pin BGA and LQFP configurations.
