This paper describes a new architecture-based DSP processor, which consists of n n mesh multiprocessor for digital signal processing. A prototype chip, RCDSP9701 has been designed and implemented using a CMOS 0. 6 µm process. This architecture has better performance compare to the traditional microprocessor solution to Digital Signal Processing. The proposed method poses remarkable flexibility compare to ASIC (Application Specified Integrated Circuits) approach for Digital Signal Processing applications. In addition, the proposed architecture is fault tolerant and suitable for parallel computing applications. In this paper, an implementation into a silicon chip of the new architecture is presented to give a better understanding of our work.
