%X <p>In design of real-time communication systems, the Worst-Case Execution Time (WCET) of software supplies pledge for the scheduling of the task, it is a creditable base that keeping the system running safely. With continuous growth of software scale and complexity of the hardware, the values of WCET estimated by determinate methods become more and more pessimistic, which greatly reduce the utilizing rate of the system resources . In order to improve the running efficiency of real time system, the article introduced a method of extreme value statistic in the estimation of WCET, and established the GPD model of WCET. The model was verified by experiments, the feasibility and the validity of this method was proven.</p>
