ABSTRACT

Multiplier is one of the most essential and fundamental components in many multimedia and Digital Signal Processing (DSP) Systems. They play very important role since they can greatly influence the performance and the power dissipation of the system. Thus, for better performance of such systems, efficient realization of multiplier is very crucial. Many DSP applications employ fixed-point arithmetic where n bit signals are multiplied by n bit coefficients. To avoid infinite growth in the word size, 2n bit products obtained must be quantized to n bits.This paper studied of radix-4 Booth Multiplier and Radix-2 Booth Multiplier. Modified Booth’s algorithm employs both addition and subtraction and also treats positive and negative operands uniformly. No special actions are required for negative numbers.
