Abstract :
This paper describes the design of a pipelined CMOS 16×16 redundant binary multiplication-and-accumulation (MAC) unit. The MAC unit uses a novel coding scheme for representing binary signed digits. The coding, integrated with the modified Booth algorithm, produces a factor of four reduction in the number of summands feeding the adder tree without preprocessing. The consequent chip layout is compact and small. Furthermore, the MAC´s pipeline stages are balanced, resulting in a clock rate exceeding 200 MHz with 0.8-μm two-level metal CMOS technology
