8-Bit Approximate Multiplier using Approximate Full Adder
Objective
The objective of this project is to design and implement an 8-bit approximate multiplier using approximate full adders for high-speed and power-efficient arithmetic operations. It focuses on reducing computational complexity and power consumption by introducing controlled approximation in the multiplier design. The circuit will be modeled and simulated to evaluate key performance parameters such as delay, area, and power. Functional verification will be performed to ensure acceptable accuracy levels for practical applications. The overall goal is to develop a low-power, high-performance approximate multiplier suitable for image processing and error-tolerant computing systems.
