چکیده
This work presents the evaluation of a new dual-core lockstep hybrid approach aimed to improve fault tolerance in microprocessors. Our takes advantage modern multicore processor resources combine software-based with custom hardware observer. The first is used duplicate data and instruction flows; meanwhile, second charge control-flow monitoring. proposal has been implemented ARM microprocessor validated low-energy proton irradiation emulated injection campaigns. results show an improvement one order magnitude cross section benchmarks tested, even considering worst case scenario.

متن کاملSelective SWIFT-R - A Flexible Software-Based Technique for Soft Error Mitigation in Low-Cost Embedded Systems
Commercial off-the-shelf microprocessors are the core of low-cost embedded systems due to their programmability and cost-effectiveness. Recent advances in electronic technologies have allowed remarkable improvements in their performance. However, they have also made microprocessors more susceptible to transient faults induced by radiation. These non-destructive events (soft errors), may cause a...
