Zunächst wird eine Analyse der Inter-Core Interferenz in Mehrkernsystemen vorgestellt. Desweiteren wird eine Analyse der Kontext-wechselkosten für nicht-inklusive Cache-Hierarchien präsentiert. Die Auswertungen beider Analysen zeigen, dass in vielen Fällen die Analysepräzision gegenüber dem State-of-the-Art verbessert wird. Abschließend wird eine Optimierung vorgestellt, die Cache-Umgehung verwendet, um die Planbarkeit des Systems zu verbessern.This thesis tackles the analysis of the worst-case timing behavior of hard real-time systems featuring multi-level cache hierarchies. First, an analysis of inter-core cache interference in multi-core systems is presented. Second, an analysis of context-switching costs for non-inclusive cache hierarchies is presented, and flaws in the previous state-of-the-art analysis are identified. The evaluations of both analyses show that, in many situations, analysis precision is significantly improved compared to the previous state-of-the-art. Finally, an optimization to improve schedulability using cache bypassing is presented.enhttps://creativecommons.org/licenses/by/4.0/Computer Science, Information and General Works::004: Computer SciencesAnalyzing the worst-case behavior of multi-level caches in concurrent real-time systemsDoctoral Thesishttps://doi.org/10.15480/882.1633510.15480/882.16335Schupp, SibylleSibylleSchuppIn reference to IEEE copyrighted material which is used with permission in this thesis, the IEEE does not endorse any of Hamburg University of Technology’s products or services.
