신뢰도를 요구하는 임베디드 시스템에서의 저전력 태스크 스케쥴링 = Power-aware Real-time Task Scheduling in Dependable Embedded Systems

다국어 초록 (Multilingual Abstract)

In this paper, we provide an adaptive power-aware checkpointing scheme for fixed priority-based DVS scheduling in dependable real-time systems. In the provided scheme, we analyze the minimum number of tolerable faults of a task and the optimal checkpointing interval in order to meet the deadline and guarantee its specified reliability. The energy-efficient voltage level at a fault arrival is also analyzed and used in the recovery of the faulty task.
