The primary goal of a VLSI engineer is to optimize power, performance, and area. This project aligns with the same objective, which is why we chose it.
The aim of our project is to design a MAC (Multiply-Accumulate) unit using approximate adders by replacing exact adders with approximate ones, in order to reduce area and power consumption.
Approximate circuits are digital circuits designed to trade off some accuracy in computation for improvements in area, power, delay, and energy efficiency. Instead of always producing mathematically exact results, these circuits intentionally allow small errors in the output, which are acceptable in certain applications.
MAC stands for Multiply-Accumulate. It is a fundamental operation used extensively in digital signal processing (DSP), machine learning, and control systems.
Approximate circuits are increasingly used in Digital Signal Processing (DSP) modules because they offer significant benefits in efficiency by accepting small, tolerable errors.
