摘要

In this paper, a reconfigurable Residue Number System (RNS) FIR filter using higher radix multiplier is proposed. The FIR filter is implemented in direct form. The binary input is converted to Residue Number System; the resultant is processed in FIR sub-filters implemented using radix-16 multiplier and finally the result is obtained in binary form. The reconfigurable structure is designed by selecting the number of taps. Thus the proposed design provides flexibility due to reconfiguration where the number of taps is varied and the design is tested for 4,8,12 and 16 taps. Low power and high speed is achieved by Residue Number System and higher radix-16 multiplier. The proposed architecture has been implemented and synthesized using Altera DE2 Cyclone II EP2C35F672C6.
