Abstract: In order to improve the portability of the parallel Digital Signal Processing(DSP) system, this paper designs a message-passing routing algorithm. It advances the efficiency of algorithm through using adjacency list to store the structure of system hardware topology and enhances information of node data flows as restrictive qualification for algorithm searching. ADSPTS101 parallel system is as an example, it implements and validates the routing algorithm using VisualDSP++ platform. Result shows that the algorithm solves the problem of message-passing in parallel DSP system effectively, enhances the performance of system, and it has more applicability in parallel DSP system.
