摘要
优先级天花板协议的研究是为了解决嵌入式实时操作系统中存在的死锁问题和优先级反转问题。通过对优先级天花板协议调度和资源分配规则的分析,从任务优先级管理和资源管理两部分详细阐述了在嵌入式实时操作系统上实现优先级天花板协议的方法,并对其失效情况做出了说明,最后给出了基于C/OS-Ⅱ的优先级天花板协议的测试原理。
In order to solve deadlock and priority inversion of embedded real-time operating system （RTOS）, priority ceiling protocol is studied. Through analyzing the schedule and resource allocation principle of priority ceiling protocol, the method to realize the priority ceiling protocol on embedded RTOS is proposed from the two parts of task priority management and resource management. Then the invalidation condition of priority ceiling protocol is illustrated. Finally test principle of priority ceiling protocol based on μ/OS-II is presented.
