Abstract
A multiplier contains an array of partial product generators, at least one new modified-Booth encoder. Corresponding to each new modified-Booth encoder, the partial product generator array includes a new adder cell. The partial product generator array receives inputs Y,. . . YN with the Y,receiving partial product generator being a new partial product generator for generating a partial product PP*(0,j). The new modified-Booth encoder receives multiplier bits and a multiplicand input Y,, and generates control signals and a carry in signal. The new adder cell is connected to the new modified-Booth encoder, the Y,receiving new partial product generator and the (j−2) row Y,receiving partial product generator and generates a partial product and an intermediate carry out signal so as to reduce the number of gate delay stages in the critical path of the multiplier.
