Reducing Response Times by Competition Based Dependencies

To ensure that time constraints in real-time systems are satisfied it is necessary to verify the real-time behavior during the design process of such systems. Schedulabilitiy analysis approaches can be used for this. The disadvantage of these methods is that sometimes the calculated bounds are an overestimation of the real behavior of the system. Therefore it is necessary to include the system contexts into the analysis to achieve tight bounds. In this paper we will introduce a system context that is based on the competition of tasks for a common resource. This dependency exists inherently in every system.
