Abstract
In this work, an efficient finite impulse response (FIR) filter using Residue Number System (RNS) is proposed. The chosen moduli set offers the advantage of shift and add approach. The proposed filter architecture is compared with an earlier proposed version of reconfigurable RNS FIR filter. The filters are synthesized using Cadence RTL compiler in UMC 90 nm technology. The performance of the filters are compared in terms of Area (A), Power (P), and Delay (T). The results show that the proposed architecture offers significant improvement in terms of area, delay and area-delay product(AT). Proposed approach is also verified functionally using Altera DSP Builder.Keywords
