Abstract :
The aim of this work is to reduce the power dissipated in high order finite impulse response (FIR) filters, while maintaining the delay unchanged. We compare in terms of performance, area, and power dissipation the implementation of a traditional FIR filter with a residue number system (RNS) based one. The resulting implementations, designed to work at the same clock rate, show that the RNS filter is smaller and consumes less power than the traditional one for a number of taps larger than eight
