ABSTRACT:
A multiplier efficiently multiplies signed or unsigned binary polynomial operands. The multiplier includes storage means for temporary storage of a current multiplier and a current multiplicand each of which being binary polynomials, one or more Booth decoders for examining multiplier bits iteratively in predetermined groups and presenting a Booth decoder output as one set of inputs to a plurality of delta generators and a partial product delta generator. Another set of inputs to the delta generators and the partial product delta generator is a predetermined group of bits from a multiplicand. The outputs of the partial product delta generator are multiplexed with outputs of the partial product register to provide inputs of an adder array. The adder array has outputs to a parallel adder which generates partial products which are then fed back to the multiplexor. The operation of the multiplier is controlled by a state machine wherein the multiplexor selects one of a plurality of inputs to the multiplexor as output depending upon the state condition of the state machine.
