A Single-Version Algorithmic Approach to Fault Tolerant Computing Using Static Redundancy

This paper describes a single-version algorithmic approach to design in fault tolerant computing in various computing systems by using static redundancy in order to mask transient bit errors in processor-memory and registers. This low-cost single-version scheme relies on a time redundancy approach. This software scheme does not intend to tolerate software design bugs. Instead of using multiple and independent versions of an application program, this single-version approach uses multiple copies of an application program. This low-cost approach is useful to tolerate various malicious code modifications and transient-faults during the run time of a computing application system without incurring any additional cost for extra hardware and extra software versions as an N-version programming scheme (NVP) or a Recovery block scheme (RBS). This proposed model is a practical and usable one that demands an affordable redundancy in time and space. The proposed scheme is capable of tolerating vari...
