Abstract: The communication cost between the processing nodes in parallel processor is the performance bottleneck of the processor. This paper presents a parallel processing system using TMS320C641X DSPs as core processor based on multi interconnection networks of PCI bus, McBSP and the packets switching network. Data of input, output and control separately flow on different networks suitable for them. The transfer efficiency is improved. This design implements the combination of high performance DSPs and high performance interconnection system.

Key words: parallel processing, DSP, interconnection networks
