Neelima Journal on Electronics Engineering 2249 – 0760 6 3 21 27 Ripple Carry Adder, Carry Look Ahead Adder, Radix-4, Radix-8, Radix-16, Modified Booth Encoding Scheme Digital multipliers are widely used in the arithmetic units of microprocessors, multimedia and digital signal processors. The main aim of this research work is to design high performance multipliers using different radix to different adders. Modified booth encoding technique is used in this proposed design, where extra partial products are reduced to half. Therefore, the accumulation stages are reduced. By this design, it significantly improves speed, area and delay which is a main objective and purpose of the study. Modified booth encoding technique improves the power delay product by using different types of adders with different radix such as radix-4, radix-8, and radix-16. The used adders are ripple carry adder and carry look-ahead adder, where these are used to know the exact difference by their comparison in terms of delay and area by using Xilinx ISE 14.5 tool with high performance parameters.
