DIGITAL FILTER REALIZATION USING IMPROVED RESIDUE NUMBER SYSTEM.
Date of Original Version
Recursive digital filter architectures using the improved residue-number-system- (RNS) based arithmetic which uses moduli which are small in value, are proposed. A scaling technique is presented which requires only log//rn look-up cycles and has an error of only left bracket s/2 right bracket , where s less than n is the number of moduli used in the scaling. With this technique it is possible to realize recursive filters with throughput rates in the range of tens of megahertz and data/coefficient accuracy of 16 bits, using only look-up tables. This is done by carrying through all the computations a small redundant residue in a separate redundant channel of at most log//2n bits in width.
