A high-speed division algorithm for residue number system

A new algorithm for one of the longstanding problems in residue number system, namely division, is presented. The algorithm is very simple. It approaches the paper-and-pencil division procedure where the quotient is selected to guarantee a non-negative remainder. This algorithm does not require sign and overflow detection, scaling, or redundant moduli. Based on computer simulation results, the algorithm is four times faster than the most recent and competitive published work by Lu and Chiang (see IEEE Trans. Compu., vol. C-41, no. 8, p. 1026-32, 1992).
