System safety through automatic high-level code transformations: an experimental evaluation

This paper deals with a software modification strategy allowing the on-line detection of transient errors. Being based on a set of rules for introducing redundancy in the high-level code, the method can be completely automated, and is particularly suited for low-cost safety-critical microprocessor-based applications. Experimental results from software and hardware fault injection campaigns are presented and discussed, demonstrating the effectiveness of the approach in terms of fault detection capabilities
