Description
Summary:A checker/corrector system has stronger fault-tolerant ability than a checker system. The design of a totally self-checking checker/corrector (TSC 3 ) circuit is considered. The TSC property for checker/corrector systems is defined. One of the critical issues in designing a TSC 3 is that the test vectors for detecting the faults in the corrector may not occur in normal operation. A self-exercising method to solve this problem is proposed. A design of self-exercising TSC 3 for a two-dimensional error-correcting code is given as an example.
