Abstract :
A Wallace tree multiplier using Booth Recoder 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 area of the Wallace tree multiplier. This is accomplished by the use of Booth algorithm and compressor adders. The coding is done in Verilog HDL and synthesized for Xilinx Virtex 6 FPGA device. The result shows that the proposed architecture is around 67 percent faster than the existing Wallace-tree multiplier, 53 percent faster than the Vedic multiplier, 22 percent faster than the radix-8 Booth multiplier, 18 percent faster than the radix-16 Booth Multiplier. In terms of area also, the proposed multiplier is much efficient.
