Abstract-In this paper, a novel unified implementation of signed/unsigned multiplication is proposed using a simple signcontrol unit together with a line of multiplexers. The proposed approach is demonstrated through a 0.18μm CMOS implementation of a 32-bit signed/unsigned multiplier. Reported results show that the proposed unified signed/unsigned implementation is very compact with only 0.45% silicon area overhead. The critical path delay of the proposed multiplier is about 3.13ns.
