Original Abstract

This paper presents two universal efficient approaches for overflow and sign detection and correction in the addition of two numbers in unsigned and signed residue number systems (RNS). Both methods are designed to be used in systems based on the moduli set {2n – 1, 2n, 2n + 1} that provides an even dynamic range. Moreover, by applying a tiny modification, these designs can be used in any system that has (2n) as one of its moduli (i.e. has an even dynamic range). The proposed methods depend on a simple structure that provides fast and accurate detection and correction of the sign and overflow. A comparison, which proves the efficiency of the proposed designs, in terms of time and area requirements is also presented.
