Abstract
An excess-3 code adde $r_tracter circuit is proposed for human friendly decimal computation. Carry lookahead (CLA) circuitry can be used to enhance decimal computation speed. The proposed excess-3 adde $r_tracter employs improved CLA and compensation circuitry recoding computation delay. The circuitry used for addition is used for subtraction without further modification. Substantial speed improvement is obtained compared to conventional designs.signs.
