Abstract: This work investigates the problem of dynamic power management and scheduling for a uniprocessor system with dynamic voltage and frequency scaling (DVFS) facilities. This one is qualified as real-time since jobs have to be executed before deadlines. In addition, it is an energy harvesting system since its supply energy is drawn from the environment. We assume that the preemptable jobs receive dynamic priorities according to the Earliest Deadline First (EDF) rule. We propose to extend the dynamic power management scheme called EDeg that must be adapted to a processor with DVFS capabilities. We show how to adjust dynamically the frequency in order to gain quality of service measured in terms of deadline miss rate.
