Abstract
A multiplier circuit for generating a product of at least first and second multiplicands includes encoding circuitry comprising a plurality of encoders. Each of the encoders is operative to receive at least a subset of bits of the first multiplicand and to generate a partial product corresponding to the subset of bits of the first multiplicand. The encoding circuitry is further operative to incorporate a negation of the product as a function of at least a first control signal supplied to the multiplier circuit. The multiplier circuit further includes summation circuitry coupled with the encoding circuitry. The summation circuitry is operative to sum each of the partial products generated by the encoding circuitry to thereby generate the product without performing post-incrementation.
