The paper addresses the problem of evaluating the effectiveness of fault hardening procedures based on software redundancy. We analyze the time and memory overhead of fine-grained and coarse-grained error detection and correction techniques. We check the impact of the involved overhead on fault coverage. The presented considerations are illustrated with fault injection experimental results.
