Abstract:
Residue Number System (RNS) based Finite Impulse Response (FIR) digital filters and
traditional FIR filters. This research is motivated by the importance of an efficient filter
implementation for digital signal processing. The comparison is done in terms of speed and
area requirement for various filter specifications. RNS based FIR filters operate more than
three times faster and consumes only about 60% of the area than traditional filter when
number of filter taps is more than 32. The area for RNS filter is increasing at a lesser rate than that for traditional resulting in lower power consumption. RNS is a nonweighted number system without carry propogation between different residue digits.This enables simultaneous parallel processing on all the digits resulting in high speed addition and multiplication in the RNS domain
