worst case execution timing (WCET)

The Worst Case Execution Time

(WCET) is the longest possible execution time of a program. This time is the maximum time for the calculation of a task. The WCET is decisive for whether a calculation is completed in time so that functions derived from it meet

theperformance of the system. WCET can be determined by measurements with real hardware

or by using static program analysis. In the measurements, the program runtime is determined by capturing the timestamps

for the program start and end. Static WCET analysis is an alternative to time difference measurement. This method is used for single-core processors.
