Abstract :
In this paper, a high-speed residue-to-binary converter for the moduli set (2k, 2k-1, 2k-1-1) is proposed. Compared to the previous converter based on this moduli set, the proposed one is 40% faster. Also, the time-complexity product is improved by 20%. Following the top-down very large scale integration design flow, the proposed converter is implemented in 0.5 micron CMOS technology. Based on this moduli set, layouts of the 8-, 16-, 32-, and 64-bit residue-to-binary converters, which can be used in further residue number system designs, are generated and simulation results obtained
