很多嵌入式控制应用都有实时性的要求。如果应用程序与安全相关，则必须确定最坏情况下的执行时间界限，以证明遵守期限。对于时序可预测性降低的高性能多核体系结构，可以通过将静态分析和时序测量相结合的混合WCET分析来计算WCET界限。本文重点研究了一种基于非侵入式指令级实时跟踪的混合型WCET分析工具。2012ACM学科分类计算机系统组织→实时系统软件及其工程→实时可调度性
Many embedded control applications have real-time requirements. If the application is safety-relevant, worst-case execution time bounds have to be determined in order to demonstrate deadline adherence. For high-performance multi-core architectures with degraded timing predictability, WCET bounds can be computed by hybrid WCET analysis which combines static analysis with timing measurements. This article focuses on a novel tool for hybrid WCET analysis based on non-intrusive instruction-level real-time tracing. 2012 ACM Subject Classification Computer systems organization → Real-time systems; Software and its engineering → Real-time schedulability
