Wallace Tree Multiplier Designs: A Performance Comparison Review

Abstract

Multiplication process is often used in digital signal processing systems, microprocessors designs, communication systems, and other application specific integrated circuits. Multipliers are complex units and play an important role in deciding the overall area, speed and power consumption of digital designs. This paper presents a comparison review of various Wallace tree multiplier designs in terms of parameters like latency, complexity and power consumption.
