In a multi-core system with shared resources, the accesses to the shared resources from several cores may experience non-deterministic arbitration delay due to resource contention. Such delay should be considered conservatively in the worst case response time (WCRT) analysis of multi-core systems. Recently, several techniques have been proposed to account for arbitration delay for shared resource...
Nowadays dangerous, repetitive or precision requiring jobs are done by robots like flying drones, industrial assembly arms or medical assistants. In all these cases, human beings can interact with the machines, therefore it is essential to guarantee that every part of the robot's software and hardware will produce a safe behavior: both the overall behavior and the local behaviors of such embedded...
Static timing analysis of a hard real-time application is necessary to ensure that task-level timing deadlines are always met. In many cases, it is preferable to include details about the operating environment to ensure precise timing analysis. However, adding an environment model increases the overall state space being analyzed, which can result in longer analysis time. In this paper, we present...
Safety-critical hard real time systems as the flight control computer in avionics or airbag control software in the automotive industry need to be validated for their correct behavior. Besides the functional correctness, timely task completion is essential, i.e. the worst-case execution time (WCET) of each task in the system has to be determined. Saarland University and AbsInt GmbH have successfully...
