Schedulability analysis of real-time systems requires the knowledge of the Worst-Case Execution Time (WCET) of each computational activity. A precise estimation of such a task parameter is quite difficult to achieve, because execution times depend on many factors, including the task structure, the system architecture details, operating system features and so on. While some of these features are not under the authors' control, selecting a proper scheduling algorithm can reduce the runtime overhead and make the WCETs smaller and more predictable.
