摘要：Digital Signal Processing functions are widely used in real time high speed applications. Those functionsare generally implemented either on ASICs with inflexibility, or on FPGAs with bottlenecks of relativelysmaller utilization factor or lower speed compared to ASIC. The proposed reconfigurable DSP processor isredolent to FPGA, but with basic fixed Common Modules (CMs) (like adders, subtractors, multipliers,scaling units, shifters) instead of CLBs. This paper introduces the development of a reconfigurable DSPprocessor that integrates different filter and transform functions. The switching between DSP functions isoccurred by reconfiguring the interconnection between CMs. Validation of the proposed reconfigurablearchitecture has been achieved on Virtex5 FPGA. The architecture provides sufficient amount of flexibility,parallelism and scalability
