Abstract : This paper presents a division algorithm for the Residue Number System which is a modification, and improvement on, the recent algorithm of Hitz and Kaltofen (1994). The relative cost of the divisions is substantially reduced rendering the RNS division feasible for computations which are not divisionintensive such as the solution of a system of linear equations of small dimension. The advantages of this algorithm over the original work of Hitz and Kaltofen lies simply in using a ceiling function in place of the floor function. This leads to a better and simpler convergence criterion and test, and, more importantly, to a simple scheme for accelerating the potentially slow early iteration of the Newtoniterationbased algorithm.
