摘要
Much research has focused on power conservation for the processor while power conservation for I/O devices has received little attention. In this paper we analyze the problem of online energy-aware I/O scheduling for hard realtime systems based on the preemptive periodic task model. We propose an online energy-aware I/O device scheduling algorithm: Energy-ef cient Device Scheduling (EEDS). The EEDS algorithm utilizes device slack to perform device power state transitions to save energy, without jeopardizing temporal correctness. An evaluation of the approach shows that it yields signi cant energy savings with respect to no Dynamic Power Management (DPM) techniques.
