The computation of the Worst Case Execution Time (WCET) is an essential step for the verification and certification of critical real-time embedded systems. The execution time at the precision of processor cycle is determined by the micro-architecture of the processor executing the programs. However, modern processors tend to be more and more complex: they are pipelined and equipped with several acceleration mechanisms, like caches, branch predictors, etc. These mechanisms introduce timing variations that must be taken into account when computing the execution time. For example, the latency of a cache access depends on rather the data that is being loaded is present (Hit) or not (Miss) in the cache. By combining the pipeline and the accelera...
