H. Siewobr, K. A. Gbolagade . RNS Overflow Detection by Operands Examination. International Journal of Computer Applications. 85, 18 ( January 2014), 1-5. DOI=10.5120/14938-2906
In this paper, a novel scheme for detecting overflow in Residue Number System (RNS) is presented. A generalized scheme for RNS overflow detection is introduced, followed by a simplified Operands Examination Method for overflow detection for the moduli set ?{2?^n-1,2^n,2^n+1}. The proposed method detects overflow in RNS addition of two numbers without pre-computing their sum. Moreover, when compared with the best known similar state of the art designs, the proposed scheme requires lesser hardware, reduces the operation size and is faster.
