Abstract

Reliability of life critical missions which is an important criterion for any system is achieved by proper fault detection techniques. Digital filters are most often integrated in modern digital signal processing systems for the processing of signals. According to Moore’s law, number of integrated circuits used in signal processing as well as communication systems are becoming more circuitous and their productions are doubling, per year. This triggered the need for fault tolerant executions. This paper replaces the conventional Error Correction Code based protection scheme to an efficient coding scheme for making the Digital FIR filters fault tolerant with less number of redundant filters and to improve the performance of the filters. Fault tolerance requires hardware redundancy and all the existing systems uses redundant modules for that. For any number of filters number of redundant modules will be least in the proposed technique.
