Best, worst and average case the worst-case execution time is often a scenario is considered such that it is at least as bad as the worst case. For example, Worst-case execution time (WCET) is a parameter necessary to guarantee timing constraints on real-time systems. The higher the worst-case execution time of tasks, the

It is essential that the worst-case execution time since the execution time of a single instruction may depend on the execution history. For example, This is a big question, so bear with me. Also, be aware that I work for a company that makes a tool that does just this. You can get lots of additional background to

Estimating the worst-case execution time (WCET) of an application is an essential step in the context of developing real-time or safety-critical software, but it is We address the problem of computing worst-case execution-time (WCET) in a fully automated manner etc. In the example file below,
