Today's automotive embedded systems comprise a multitude of functionalities, many with complex timing requirements. Besides task specific timing requirements, such applications often have timing requirements for the propagation of data through a chain of tasks. An important metric for control applications is the data age, which is addressed in this paper. The analysis of such systems is non-trivial...
Fixed Priority Scheduling (FPS) is the de facto standard in industry and it is the scheduling algorithm used in OSEK/AUTOSAR. Applications in such systems are compositions of so-called runnables, the functional entities of the system. Runnables are mapped to operating system tasks during system synthesis. In order to improve system performance it is proposed to execute runnables non-preemptively while...
