Both priority inheritance protocol and priority ceiling protocol are common solutions to priority inversion in real-time system ( RTOS ). 优先级继承协议和天花板优先级协议都可在一定程度上解决实时系统(RTOS)中的优先级倒置。
At present, an approach solving solution is priority ceiling protocol ordinarily, but the resources efficiency of the system based on the protocol is low. 目前通常采用优先级上限协议(PCP)解决策略,但该协议的系统资源利用率较低。
Research on priority ceiling protocol of embedded RTOS 嵌入式RTOS优先级天花板协议研究
Testing whether the modified operating system support the priority ceiling protocol which the OSEK OS specification provided. 测试是否支持OSEKOS规范规定的优先级上限协议(PCP)。
Based on the Priority Ceiling Protocol(PCP) in OSEK standard, we introduce improvement techniques, treating internal resources and external resources differently, which in the mode of mixed scheduling, greatly reduces the overhead of resource allocation in context-switch. 在OSEK标准提出的优先级置顶协议基础上,本文提出了面向内部和外部资源的两种不同的优化方法,在操作系统处于混合调度模式下,这种改进显著地减少了调度中资源分配的开销。
