energy-aware dual-mode voltage scaling for weakly hard real-time systems
In this paper we study the problem of minimizing energy while ensuring the designated QoS requirements for weakly hard realtime systems on a dual-mode variable voltage processor. The QoS is quantified with the (m, k)-constraints. We proposed a dynamic scheduling strategy, based on pattern variation and the enhanced dual priority scheduling, to guarantee the (m, k)-constraints while optimizing the energy consumption. The simulation results demonstrate that our proposed techniques can achieve significant energy saving performance while ensuring the (m, k)-guarantee.
