Behavior-Based Fault Monitoring

Abstract

An approach is developed which exploits the deterministic behavior of a processor to perform concurrent fault monitoring. A very low cost and highly effective technique is called Continuous Signature Monitoring (CSM), has been developed. This technique is capable of detecting transients with very low detection latency, and requires very minimal memory overhead and performance penalty. This technique has been applied to both CISC and RISC type processors. Both analytical and experimental results have been obtained in validating the effectiveness of the approach. CSM has been adopted by two aerospace companies in their design of a 32-bit RISC processor targeted for avionics and space applications. It appears that the signature monitoring technique can be extended to detect computer viruses as well via a form of program encryption.
