Multiplication is one of the most common arithmetic operations employed in digital systems, but multipliers are the most time, area, and power consum ing circuits. Improvement in any of these parameters can be advantageous for improving the efficiency of the circuit. The ever increasing need for development of efficient and high speed multipliers has motivated several researchers to go a step ahead and present some novel approach. This paper presents an approach towards the reduction of delay in the Wallace tree multipliers by using 4:2 compressors along with full - adders and half - adders, in the partial product reduction stage; and employing Kogge - Stone a dder for the final addition. The proposed multiplier has been designed using Xilinx ISE Design Suite 14.7 and implemented for Spartan 3 FPGA.
