Performance Analysis for Optimized ALU Design Using Carry Select Adder and Vedic Multiplier

An Arithmetic Logic Unit (ALU) is a fundamental building block of modern processors and digital systems, responsible for performing arithmetic and logical operations. The overall performance of a processor is highly dependent on the speed, area, and power efficiency of its ALU. Conventional ALU designs typically employ ripple carry adders and array multipliers, which introduce significant propagation delay and increased power consumption. This project presents a performance-optimized ALU architecture using a Carry Select Adder (CSLA) for fast addition and a Vedic Multiplier based on the Urdhva Tiryakbhyam algorithm for high-speed multiplication. By integrating these optimized arithmetic units, the proposed ALU achieves reduced delay, improved throughput, and better power efficiency. The design is implemented using Verilog HDL and evaluated in terms of speed, area, and power, demonstrating its suitability for high-performance VLSI and DSP applications.
