Layout design and simulation of fault tolerant triple modular redundant ALU system

摘要

Reliability is one of the most critical factors that is to be considered during the designing phase of any product. There are many factors that contribute to make a system more reliable in terms of area, power, operating frequency and accuracy. This paper proposes the design of a 4bit fault tolerant ALU system using backend designing. Parallel processing along with triple modular redundancy (TMR) has been used to increase the operating speed of the system and also to make the system fault tolerant and accurate. The backend designing has been done using Micro-wind 3.1.7
