DESIGN OF AREA AND POWER EFFICIENT BOOTHMULTIPLIERS USING MODIFIED BOOTH ENCODING

Abstract

Abstract: Redundant Binary Partial Product Generator technique are used to reduce by one row the maximum height of thepartial product array generated by a radix16 Modified Booth Encoded multiplier, without any raise in the delay of thepartial product creation Block. In this paper, we describe an optimization for binary radix-4 modified Booth recodedmultipliers to reduce the maximum height of the partial product columns to [n/4] for n = 64-bit unsigned operands. This isin contrast to the conventional maximum height of [(n + 1)/4]. Therefore, a reduction of one unit in the maximum height isachieved. This Arithmetic multipliers increase the performance of ALU and Processors. We evaluate the proposed approachby comparison with Normal Booth Multiplier. Logic synthesis showed its efficiency in terms of area, delay and power.Simulation results show that the proposed Multiplier based designs significantly improve the area, delay and powerconsumption when the word length of each operand in the multiplier is 64 & n-bits. The proposed architecture of this paperanalysis the delay and area using Xilinx 14.2.Keywords: Modified Booth Encoding, Radix-16, Pipeline, Multiplier, Enhanced, Carry Select Adder, Binary ExcessConverter. ------
