SM320VC5421-EP 增强型产品定点数字信号处理器

The 320VC5421 fixed-point digital signal processor (DSP) is a dual-core solution running at 200-MIPS performance. The 5421 consists of two DSP subsystems capable of core-to-core communications and a 128K-word zero-wait-state on-chip program memory shared by the two DSP subsystems. Each subsystem consists of one 54x DSP core, 32K-word program/data DARAM, 32K-word data SARAM, 2K-word ROM, three multichannel serial interfaces, xDMA logic, one timer, one APLL, and other miscellaneous circuitry.

The 5421 also contains a host-port interface (HPI) that allows the 5421 to be viewed as a memory-mapped peripheral to a host processor. The 5421 is pin-compatible with the TMS320VC5420.

Each subsystem has its separate program and data spaces, allowing simultaneous accesses to program instructions and data
