Abstract

In this paper, we propose adaptive scheduling and bandwidth allocation techniques to efficiently integrate multimedia tasks for MPEG applications in hard real-time systems. The paper describes a server-based mechanism for assigning the CPU resource to hard real-time tasks and multimedia tasks, respectively. Especially for MPEG video applications, we show how to dynamically control the fraction of the CPU bandwidth allocated to each multimedia task according to the priority. The primary purpose of these techniques is to minimize the mean tardiness of multimedia tasks while satisfying the timing constraints of hard real-time tasks. The performance of the proposed scheduling techniques is compared with that of similar mechanisms through simulation experiments.
