Design Of All-purpose DSP Parallel Processing Systems Based On Standard Buses

This paper deals with techniques of designing all-purpose DSPs parallel processing systems, aims to develop signal processing systems which are more reconstructed and more scalable. On the one hand, we can meet the request of processing tasks changes and algorithm development through flexible software programming, on the other hand , we can meet the request of processing scale changes through simple hardware extention . First, Techniques of DSPs parallel processing are generally introduced. Then two structures of standard buses interfaces are presented. One is based on PCI bus, the other is based on VME bus. The two kind of buses have features of each own, either can be chosen as the final interface of DSPs board according to practical applications. The method of implementing asynchronous communication between DSPs and standard buses through FIFOs is discussed in detail and many simulation results of functional modules are also given.
