| In this paper, we propose a timing analysis approach for preemptive multi-tasking real-time systems with caches. The approach focuses on the cache reload overhead caused by preemptions. The Worst Case Response Time (WCRT) of each task is estimated by incorporating cache reload overhead. After acquiring the WCRT of each task, we can further analyze the schedulability of the system. Four sets of applications are used to exhibit the performance of our approach. The experimental results show that our approach can reduce the estimate of WCRT up to 44% over prior state-of-the-art. |
