The Design and Implementation of MPI Based on Link DMA
The demand of processing speed in modern digital signal processing is huge and requires more computational power than a single processor can provide. To address these demands, distributed and parallel processing in embedded systems is becoming a requirement. So it is essential to do research on algorithm and the parallel programming in the parallel embedded system. MPI (message passing interface) is one of the most important parallel programming standards. Porting MPI to the embedded system will enhance application portability and make parallel programming much easier. This paper presents a novel design and implementation of MPI based on link DMA for DSP-based systems. Through computation the value of and PingPong, the results show that the implementation is suitable for parallel programming, especially suitable for large volume of data.
