Abstract

Several dependability improvement methods using multiple-core based systems have been proposed. In this paper, the lock-step pair scheme that is popular in car companies these days, the traditional TMR-spare scheme, and our proposed DTTR (Duplication with Temporary TMR and Reconfiguration) scheme are modeled using the Markov chains considering both permanent and transient faults, and are compared in the viewpoint of the average system failure rate.
