IEEE Transactions on Dependable and Secure Computing, 13(4), 502–508.1545-5971https://hdl.handle.net/10016/34015Integrity assurance of configuration data has a significant impact on microcontroller-based systems reliability. This is especially true when running applications driven by events which behavior is tightly coupled to this kind of data. This work proposes a new hybrid technique that combines hardware and software resources for detecting and recovering soft-errors in system configuration data. Our approach is based on the utilization of a common built-in microcontroller resource (timer) that works jointly with a software-based technique, which is responsible to periodically refresh the configuration data. The experiments demonstrate that non-destructive single event effects can be effectively mitigated with reduced overheads. Results show an important increase in fault coverage for SEUs and SETs, about one order of magnitude.7eng© 2015 IEEE.Single Event Upset (Seu)Single Event Transient (Set)Fault toleranceSoft error mitigationRadiation effectsCo-design approachEmbedded systemsEmulationInjectionresearch articleElectrónicaTelecomunicacioneshttps://doi.org/10.1109/TDSC.2014.2382593open access5024508IEEE Transactions on Dependable and Secure Computing13AR/0000018280
