Most of the applications require hard real time signal/data processing potentiality for which fast and dedicated VLSI architectures are the best solution. But designing such circuits lead to high occurrences of failure in the system. Hence there is a critical need for fault tolerance techniques for VLSI designs to increase the reliability of the system. Redundancy techniques are implemented widely...
Triple modular redundancy (TMR) is a well-known technique for building fault-tolerant systems. In TMR, a module unit is triplicated, and the outputs of these three units are compared by a voter. In this paper we consider systems that consist of multiple TMR units in series. Only recently has it been found that even such simple systems can be configured into various structures. We propose (i) a method...
Module redundancy is often used as a method of construction a reliable system. TMR is used as the method of improving reliability by module redundancy. However, TMR does not decide correct result when two of three modules fail. Therefore, we proposed a new architecture of voting termed as Stateful TMR. It uses the result of TMR and State of the history, to select the most reliable module. By the simulation,...
