摘要

在硬实时多任务系统中，将面向wcet的代码优化应用于单个任务可能不会导致系统可调度性方面的最佳结果。我们提出了一种基于整数线性规划的方法，该方法能够对具有固定优先级的周期性任务集执行可调度性感知的代码优化。我们通过使用英飞凌TriCore微控制器的静态指令SPM优化来评估我们的方法。

Schedulability Aware WCET-Optimization of Periodic Preemptive Hard Real-Time Multitasking Systems

In hard real-time multitasking systems, applying WCET-oriented code optimizations to individual tasks may not lead to optimal results with regard to the system's schedulability. We propose an approach based on Integer-Linear Programming which is able to perform schedulability aware code optimizations for periodic task sets with fixed priorities. We evaluate our approach by using a static instruction SPM optimization for the Infineon TriCore microcontroller.
