Overview
The TMS320VC5421ZGU200 is a high-performance, fixed-point digital signal processor (DSP) developed by Texas Instruments. This dual-core DSP operates at 200-MIPS performance, making it suitable for demanding applications such as remote data access, voice-over IP subsystems, and other complex signal processing tasks. The processor features two 54x DSP cores, each with its own program and data spaces, allowing for simultaneous accesses to program instructions and data. This architecture supports powerful arithmetic, logic, and bit-manipulation operations, all of which can be performed in a single machine cycle.
