Recent research on embedded real-time systems has focused on dynamic power management for fault-tolerance or dependability. In this paper, we provide an adaptive checkpointing scheme for fixed priority-based DVS scheduling in dependable real-time systems. Since there are some trade-offs in selection of dynamic processor scaling in terms of energy consumption and task reliability, we provide an adaptive energy-aware scaling assignment scheme with the feasibility test for fixed-priority scheduling with checkpointing. In the provided scheme, we analyze the number of tolerable faults of a task and the optimal checkpointing interval in order to meet the deadline and guarantee its specified reliability. The feasibility analysis of the fixed priority-based scheduling algorithm in dependable real-time systems is provided as well.
