Abstract
A multiplier circuit to receive a multiplier and a multiplicand comprises at least one Booth encoder circuit to encode a plurality of multiplier bits into four encoded outputs. The encoded outputs select Booth-multiply functions. The circuit also includes a plurality of multiplexer circuits, one multiplexer circuit for each bit of the multiplicand. The at least one of the plurality multiplexer circuits includes four pass gates coupled to receive a multiplicand bit, a complement of the multiplicand bit, multiplexed data from a next lower order multiplexer circuit and the encoded outputs of the Booth encoder circuit outputs to provide one bit of a partial product at a multiplexer output.
