The Application of MPI-TigerSHARC in SAR Processing System

The demand of processing speed in SAR signal processing is huge and requires more computational power than what a single processor can provide. To address these demands, an implementation of MPI (Message Passing Interface) based on link DMA for TigerSHARC DSPs is introduced in this paper. Porting MPI to the embedded system will enhance application portability and make parallel programming much easier. This paper presents a real application of range-Doppler algorithm in SAR processing system. The result shows that MPI is suitable for parallel programming, especially suitable for processing large volume of data.
