    Abstract

    This paper proposes the novel programmable digital finite impulse response (FIR) filters for low-power and high-performance applications. The architecture is based on the higher radix recoding scheme which specifically targets the reduction of power consumption by decreasing partial products and precomputation sharing in each partial product. We extend higher radix recoding scheme with secondary radix recoding to further improve performance by reducing the propagation delay of precomputing odd multiples of the multiplicand. A 10-tap programmable FIR filter based on proposed schemes was design in TSMC 0.18-μm technology. The performance and power consumption of the proposed schemes can improve about 40.9∼65.5% and 28.3∼50.2% over existing designs.
