Evaluating Compiler-Based Reliability with Radiation Fault Injection

Compiler-based fault tolerance is a cost-effective and flexible family of solutions that transparently improves software reliability. This paper evaluates a compiler tool for fault detection via laser injection and α-particle exposure. A novel memory allocation strategy is proposed to mitigate the effects of multi-bit upsets. We integrated the detection mechanism with a recovery solution based on mixed-criticality scheduling. The results demonstrate the error detection and recovery capabilities in realistic scenarios: reducing undetected errors, enhancing system reliability, and advancing software-implemented fault tolerance.
