Abstract

A digital processing system including a central processing unit (CPU) and a digital signal processor (DSP) is optimized for digital signal processing applications, providing the central processing unit and digital signal processor with equal access to system resources such as system memory and connected I/O devices. The digital processing system includes two high-performance processor busses: one processor bus providing connection for one to four CPUs; the other processor bus providing connection for up to four DSPs. An advanced multi-ported memory controller interconnects the two processor busses with system memory and a system I/O bus, providing the CPUs and DSPs with equal and uniform access to all system memory and I/O resources.
