Abstract: The PowerPC 7400/7410 processors are new generation PowerPC G4 processors with high-performance AltiVec Unit, which is 128-bits wide and benefit dealing with high data throughput, so it fulfils the requirement doing DSP and strongly substitute DSP .This paper discusses an improved model, by making an analysis on three parallel architectures with four PowerPC processors and comparing their performances in Radar DSP.
