Probabilistic analysis are considered nowadays an interesting solution for real-time systems as the probabilityof appearance of worst-case values is small (10−45 per hour of functioning) compared to the acceptedprobability of failure (10−9 per hour of functioning for the highest safety level in avionics). In order to takeinto account this...

During the last years the arrival of multi-core processors or many-core processors as well as the increased complexity of programs have made more difficult the estimation of the worst case execution times (WCETs) of programs. The existing methods may produce estimates that are too pessimistic for some systems. As result new analyses based on...

The arrival of modern and more complex processors (e.g., use of caches, multi-and many-core processors) increases the timing variability of tasks, i.e., the worst case execution time (WCET) is becoming significantly larger, while the probability of appearance of a worst case execution time is extremely low. Approaches taking into account this...
