In this paper, the authors present a system level dynamic scheduling algorithm to minimize the energy consumption by the DVS processor and multiple non-DVS peripheral devices in a hard real-time system. They show that the previous work which adopts the critical speed as the lower bound for scaling might not be most energy efficient when the energy overhead of shutting-down/ waking-up is not negligible. Moreover, the widely used statically defined break even idle time might not be overall energy efficient due to its independence of job execution situations.
