Paper Abstract

Multipliers using different number representation systems have different power/area/delay characteristics. This paper studies the effects of number representations on power consumption and proposes optimization techniques for two's-complement multipliers. By examining existing radix-4 recoding design schemes, two power-improved designs are proposed for standard cell CMOS technology. With new recoding schemes, the power efficiency of radix-4 multipliers versus radix-2 multipliers are re-investigated. To utilize the power efficiency of sign-magnitude representation, number representation conversion schemes are proposed. For a typical data set from application djpeg, the conversion schemes consume less than 30% power of the baseline schemes.
