“…Although both permanent and transient faults may occur during task execution, transient faults are found more frequent than permanent faults [14,19]. Hence, in this paper, we focus on transient faults.…”

“…Dynamic Voltage and Frequency Scaling (DVFS) technique, which dynamically lowers down the supply voltage and working frequency, is widely used for power/energy management. However, existing work [19,28] has shown that transient fault rate increases when the supply voltage on the chip scales down. In other words, lowering down system's supply voltage potentially degrades the system's reliability.…”

This paper studies the energy minimization problem in mixed-criticality systems that have stringent reliability and deadline constraints. We first analyze the resource demand of a mixed-criticality task set that has both reliability and deadline requirements. Based on the analysis, we present a heuristic task scheduling algorithm that minimizes system's energy consumption and at the same time also guarantees system's reliability and deadline constraints. Extensive experiments are conducted to evaluate and validate the performance of the proposed algorithm. The empirical results show that the algorithm further improves energy saving by up to 10% compared with the approaches proposed in our earlier work.
