An Energy Aware Scheduling for Reconfigurable Heterogeneous Systems

One of the major challenges of computer system design is the management and conservation of energy while satisfying QoS requirements. Recently, Dynamic Voltage and Frequency Scaling (DVFS) has been integrated to various embedded processors as a mean to increase the battery life without affecting the responsiveness of tasks. This paper proposes an enhancement for I-codesign methodology [1] optimizing the energy consumption of the designed system.We propose an energy aware real-time scheduling algorithm. This algorithm makes use of the defferable server for the scheduling of aperiodic tasks along with DVFS. Simulation results demonstrate a decrease in the resulting energy consumption compared to the previously published work.
