Towards Multicore WCET Analysis
Simon Wegener · DROPS (Schloss Dagstuhl – Leibniz Center for Informatics) · 2017
AbsInt is the leading provider of commercial tools for static code-level timing analysis. Its aiT Worst-Case Execution Time Analyzer computes tight bounds for the WCET of tasks in embedded real-time systems. However, the results only incorporate the core-local latencies, i.e. interference delays due to other cores in a multicore system are ignored. This paper presents some of the work we have done towards multicore WCET analysis. We look into both static and measurement-based timing analysis for COTS multicore systems.
