A High Speed Wallace Tree Multiplier Using Modified Booth Algorithm for Fast Arithmetic Circuits

A Wallace tree multiplier using modified booth algorithm is proposed in this paper. It is an improved version of tree based Wallace tree multiplier architecture. This paper aims at additional reduction of latency and power consumption of the Wallace tree multiplier. This is accomplished by the use of booth algorithm, 5:2, 4:2, and 3:2 compressor adders. An efficient Verilog HDL code has been written, successfully simulated and synthesized for Xilinx FPGA vertex-6 low power (Xc6vlx75tl-1Lff484) device, using Xilinx 12.2 ISE and XST. The result shows that the proposed architecture is around 67% faster than the existing Wallace-tree multiplier.
