Design and implementation of embedded parallel DSP software poses various challenges due to the complexities posed by the application as well as heterogeneous nature of the platform. One of most issues with regards to such system is communication between processor. In this paper, we present a reusable message passing software framework to make application level code more portable. A dataflow based communication routing mechanism is introduced and integrated in the framework to make the configuration of communication and data path more flexible. Inter-processor communication model and hardware platform topology model are used for the design of shortest path routing algorithm for the needs of creating routing table in which the routing information is stored for each DSP node. Finally, the software framework is applied to an ADSP-TS101 DSP multi-processors platform.
