They propose a genetic algorithm for finding a voter checking schedule that maximises the reliability of TMR-MER systems. They demonstrate that system reliability is improved when the more vulnerable components are checked more frequently than when they are checked in round-robin order. In this study, the authors outline an approach for computing the reliability of TMR-MER systems that consist of finitely many components. However, the order in which TMR voters are checked inevitably impacts the overall system reliability. By triplicating components and voting on their outputs, TMR helps localise configuration memory errors, and by reconfiguring faulty components, MER swiftly corrects them. These are commonly dealt with using triple modular redundancy (TMR) and module-based configuration memory error recovery (MER). Field-programmable gate arrays are susceptible to radiation-induced single event upsets.
