Reliable and low error dual modular redundancy FIR filter with wide protection window

Abstract

A reliable and low error dual modular redundancy FIR filter with wide protection window has been proposed in this paper. We improved the feedback mechanism by using a multiplexer to recover the soft error struck module from error immediately. The recovering time of soft error struck module can be shortened 87.18%, and the output error rate can be lowered by 4.5 times.
