Due to performance issues commercial off the shelf components are becoming more and more appealing in application fields where fault tolerant computing is mandatory. As a result, to cope with the intrinsic unreliability of such components against certain fault types like those induced by ionizing radiations, cost-effective fault tolerant architectures are needed. In this paper, the authors present an in-depth experimental evaluation of a hybrid architecture to detect transient faults affecting microprocessors. The architecture leverages an hypervisor-based task-level redundancy scheme that operates in conjunction with a custom-developed hardware module.
