Hard real-time embedded systems need to guarantee that tasks always meet their deadlines. Exact schedulability tests can guarantee this for fixed-priority, preemptively scheduled systems even under the tightest resource constraints. However, these tests are pseudo-polynomial in complexity. This can become a limiting factor in open systems where it might be(More)
In this paper, we consider multimedia Quality-of-Service (QoS) in resource constrained embedded systems, where scalable applications are structured as directed acyclic graphs of tasks, which communicate via shared buffers. Scalable multimedia applications allow to trade quality for resource usage during run-time. We present two QoS problems: (i) temporal(More)
