Also Available Domains Arithmetic Core|Xilinx ISE

Project Code :TVMATO463

Objective

The main aim of this paper is to improve the speed and reduce the area for compressor architecture. This paper presents two novel approximate 4:2 compressor architectures for reducing area, delay and power dissipation in multipliers in which more than two stages of cascaded compressors are required for partial product accumulation

Abstract

Energy-efficient computing is a much needed technological advantage for future. Approximate or inexact computing is a computing paradigm that can trade energy and computing time with accuracy of output. This project proposes the approximate design and analysis of two approximate compressors with reduced area, delay and power.

The proposed compressors are utilized to implement 8x8 and 16x16 Dadda multipliers. These multipliers have high accuracy when compared with state-of-the-art approximate multipliers. The effectiveness of the proposed design is synthesized and simulated using Xilinx Vivado software.
