Parallel Software Design on High-Speed DSP Board Based on ADSP-TS101S

The SAR real-time imaging process is a typical pipelined structure, which includes many complicated algorithms such as FFT. Because of their complexity, for large data rate, it takes too long time to implement in real-time processing with single current DSP, which needs multi-DSP for parallel computing. So we developed multi-DSP platform based on ADSP-TS101S, and several parallel software programming methods on such loose coupling architecture multi-DSP platform is studied. Also 16 k complex points float point FFT algorithm is implemented as an example, which testified the briefness and correctness of these methods.
