Objective

this research presents a novel approach to designing Dadda multipliers using XOR-XNOR cell based hybrid logic full adders, aiming to achieve low power consumption and high speed operation

Abstract

This project presents the design and implementation of a low-power, high-speed Dadda multiplier using XOR-XNOR cell-based hybrid logic full adders. The Dadda multiplier architecture is optimized to reduce critical path delay and minimize power consumption while maintaining high computational accuracy. By incorporating XOR-XNOR hybrid full adder cells, the design efficiently balances speed and energy efficiency, allowing fast arithmetic operations with reduced switching activity. The multiplier is implemented using advanced CMOS technology and analyzed for key performance metrics such as propagation delay, power consumption, area, and overall throughput. Simulation results demonstrate that the proposed multiplier achieves significant improvements in speed and energy efficiency compared to conventional full adder-based designs. The scalable architecture makes it suitable for integration into digital signal processing units, high-speed processors, and other VLSI applications requiring high-performance arithmetic computation.
