Abstract: A parallel radar signal processor framework based on StarFabric interconnection is proposed, and transfer performance of the StarFabric network analyzed by mathematical modeling. At the same time, digital signal processing(DSP) module and other module were designed. DSP module integrates 8 C64x DSP and 2GB memory. Other modules have the same connection interface but with different function circuit. The framework and the modules had been applied in a SAR jamming signal processor.
