Originální abstrakt

Two novel designs of residue number system adders corresponding moduli 2n–1, 2n+1 are presented in this paper. Both designs are based on prefix computation idea, which was inspired from the technique used in carry look-ahead adder (CLA). This prefix computation speeds up the addition-correction process corresponding to each modulo. The proposed modular adders were designed in such a way to be efficiently implemented on Spartan-3 field programmable gate array (FPGA) board. The implementation results showed time, area savings up to 44.7%, 14.3%, respectively, which indicates that these adders are very effective for designs with critical timing requirements.
