本文分析了在OSEK操作系统中天花板优先级协议存在的缺陷,提出了一个改进后的优先级天花板协议,此方案成功解决了优先级反转问题,并改善了在任务调度时的实时性。本文介绍了协议的原理,最后通过实验数据证明方案可行。
This paper analyzes the shortcomings of OSIK OSC protocol and proposes an improved priority ceiling protocol. This solution successfully solves the priority inversion problem and improves the real-time performance of the task scheduling. This paper introduces the principle of the protocol, and finally proves that the scheme is feasible through experimental data.
