Design Of High Performance Configurable Radix-4 Booth Multiplier Using Cadence Tools

Abstract

Fast multipliers are crucial in digital signal processing systems. The speed of multiply operation is of great importance in digital signal processors and general purpose processors especially since the media processing took off. As the need for efficient design is increasing without compromising the performance, industry has to concentrate on the tradeoffs. Here, a modified Booth multiplier is implemented using an algorithm that reduces the number of partial Products to be generated using the fastest multiplication algorithm. In this work, 8X8 multipliers with maximum range of input from -128 to +127 and negative numbers represented in 2’s complement form can be used. Booth Encoder i.e., Partial Product Generator and Hybrid adder are used for the design of modified booth multiplier to achieve minimum delay and less area.
