摘要 程序最坏执行时间是实时系统可调度分析的基础,同时也是对系统进行性能分析,提前发现系统瓶颈的重要依据。本文首先论述了程序最坏执行时间(WCET)分析计算的主要方法,然后介绍了主要的测试工具及其应用情况,最后针对程序最坏执行时间的工程应用提出可行建议。 Worst-Case Execute Time(WCET) provides foundmental informantion for schedubility analysis when disigning a real-time system.It also provides important information for system analysis to find out performance bottleneck when verifying.This paper first introduces the main methods in WCET analysing,then gives the instruction of the tools used to test the WECT in project appliction.At the end of the paper a useful advice is provided.
