Dynamic power management has become essential for battery-driven embedded systems. This paper explores how to efficiently and effectively reduce the energy consumption of a device (system) for serving multiple event streams. Considering two different preemptive scheduling, i.e., earliest deadline first and fixed priority, we propose new method to adaptively control the power mode of the device according to historical arrivals of events. Our method can not only tackle arbitrary event arrivals but also provide hard real-time guarantees with respect to both timing and backlog constraints. Simulation results are presented as well to demonstrate the effectiveness of our approach.
