For mission critical real-time applications, such assatellite and surveillance systems, a high level of reliabilityis desired as well as low energy consumption. Inthis paper, we propose a general system power modeland explore the optimal speed setting to minimize systemenergy consumption for an Optimistic TMR (OTMR)scheme. The performance of OTMR is compared with thatof TMR and Duplex with respect to energy and reliability.The results show that OTMR is always better than TMRby achieving higher levels of reliability and consumingless energy. With checkpoint overhead and recovery, Duplexis not applicable when system load is high. However,Duplex may be more energy efficient than OTMR dependingon system static power and checkpointing overhead.Moreover, with one recovery section, Duplex achievescomparable levels of reliability as that of OTMR.
