Reactive-TMR (R-TMR) counters this by isolating faulty cores, handling both transient and permanent faults. However, the lightweight hardware required by R-TMR not only increases complexity but also becomes a single point of failure itself. To bypass isolated node constraints, this paper proposes a Fault Tolerance and Isolation TMR (FTI-TMR) algorithm for interconnected multicore systems. By constructing a stability metric to identify the most reliable nodes in the system, which then perform periodic diagnostics to isolate permanent faults. Experimental results show that FTI-TMR reduces task workload by approximately 30% compared with baseline TMR while achieving higher permanent fault coverage.","short_abstract":"Two-Phase TMR conserves energy by partitioning redundancy operations into two stages and making the execution of the third task copy optional, yet it remains susceptible to permanent faults.
