Les tâches périodiques en temps quasi réel, très répandues dans les applications de streaming multimédia, ont des délais plus longs que les intervalles de saisie grâce à la mise en mémoire tampon. Pour de telles applications, les planifications conventionnelles basées sur des trames ne peuvent pas réaliser la planification optimale en raison de leurs hypothèses de délais à courte vue. Pour réaliser des exécutions globalement économes en énergie de ces applications, nous proposons un nouvel algorithme de planification de tâches, qui tire parti des longs délais. Nous confirmons que notre approche peut tirer parti du délai plus long et réduire la consommation électrique moyenne jusqu'à 18 %.

Abstract: Near real-time periodic tasks, which are popular in multimedia streaming applications, have deadline periods that are longer than the input intervals thanks to buffering. For such applications, the conventional frame-based schedulings cannot realize the optimal scheduling due to their shortsighted deadline assumptions. To realize globally energy-efficient executions of these applications, we propose a novel task scheduling algorithm, which takes advantage of the long deadline period. We confirm our approach can take advantage of the longer deadline period and reduce the average power consumption by up to 18%.
