Efficient parallel digital signal processing algorithms for hypercube-connected multicomputers
In this thesis, efficient parallelization of Digital Signal Processing (DSP) algorithms, (FFT, FHT and FCT), on multicomputers implementing the hypercube interconnection topology are investigated. The proposed algorithms, maintain perfect load-balance, minimize communication overhead, can overlap communications with computations and achieve regular computational patterns. The proposed parallel algorithms are implemented on Intel’s iPSC/2^ hypercube multicomputer with 32 processors. High efficiency and almost linear speedup values are obtained for even small size problems.
