Abstract :
In this paper, a repairable ability of triple modular redundancy TMR system was presented. There were two sets of processing units, which were set up in each module of TMR system. When one of modules in the TMR system was failure, the backup processing unit could be activated and the TMR system was reconstructed. Through analysis and testing, the method, which was proposed in this paper, could effectively improve system reliability.
