Optimization of Power and Area Using VLSI Implementation of MAC Unit Based on Additive Multiply Module

The development of Digital Signal Processors (DSPs), graphical systems, Field Programmable Gate Arrays (FPGAs)/ Application-Specific Integrated Circuits (ASICs), and multimedia systems all rely heavily on digital circuits. The need for high-precision fixed-point or floating-point multipliers suitable for Very Large-Scale Integration (VLSI) implementation in high-speed DSP applications is developing rapidly. An integral part of any digital system is the multiplier. In digital systems as well as signal processing, the adder and multiplier seem to be the fundamental arithmetic units. Problems arise when using a multiplier in the realms of area, power, complexity, and speed. This paper details a more efficient MAC (Multiply- Accumulate) multiplier that has been tuned for space usage. The proposed design is more efficient, takes up less room, and has lower latency than conventional designs. The performance of the Additive Multiply Module (AMM) multiplier is measured against that of existing multipliers, where it serves as a module in the MAC reducing area and delay.
