An energy-aware dynamic scheduling algorithm for hard real-time systems
Based on the Earliest Deadline First policy guaranteeing timeliness for hard real-time systems, we propose an enhanced EDF algorithm that varies distinct processor modes with time. Processor modes are determined by supply voltage, frequency and performance requirements, allowing for discrete control of the processors' energy consumption. Thus, processors using the enhanced policy will dissipate less energy and, at the same time, adhere to the deadlines of hard real-time systems.
