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)
Exact schedulability tests for fixed-priority preemptively scheduled systems are pseudo-polynomial in complexity. A linear-time sufficient test [1,2] has therefore been developed to estimate response-time upper bounds. In line with utilization-based sufficient tests, we propose to improve this test for task sets with harmonically related task periods.(More)
