Abstract :
Design and implementation of a low-power and low-cost booth-shift/add multiplexer-based singed multiplier is presented. The main blocks of the circuit are constructed with some simple low-power structures. It includes multiplexer-based booth encoder and singed shifter blocks, multiplexer-based Manchester adder, an optimized and compact structure of control unit, and a low-power structure for full adder. The architecture has been successfully synthesized and verified using Xilinx ISE 11 and Spartan-3 FPGA. The results obtained by Xilinx Power Estimator (XPE) show that the proposed method has 58mW power consumption in 50MHz operation frequency.
