Resiliency-aware scheduling: Resource allocation for hardened computation on configurable devices

The number of configurable systems deployed in hostile environments continues to rise. This, along with decreasing geometries and lower operating voltages leads to an expected increase in transient errors. This paper presents Resiliency-aware Scheduling, a novel approach to resource allocation for hardening computations on configurable systems. Using modular and replicated functional units called hybrid TMR that exploit a computation´s Intrinsic Resiliency, our results show that for designs with similar performance, RaS exhibits a 60% area savings over a traditional TMR configuration with the same operation coverage.
