Performance Analysis of Different Multipliers

Abstract

Multiplication is one of the most important fundamental operations in applications such as Digital Signal Processing and in ALU of the microprocessors. Since multiplication dominates the execution time and power consumption of most of the digital signal processing applications, high speed and low power multipliers are essential for next generation processors.

In this study we realized that, with proper optimization the performance of the multipliers can be increased significantly, irrespective of the type. We also realized that array multiplier occupies less area and it is moderate in various parameters when compared with other multipliers.

This paper presents a detailed study of performance comparison of different types of multipliers such as Array Multiplier, Carry Save Multiplier, Wallace Tree Multiplier and Baugh Woolley Multiplier. The simulations were performed using Xilinx 14.7 software tool.
