摘要

提高实时性是实时操作系统(RTOS)研究的核心问题之一。任务上下文切换时间是影响实时操作系统实时性的重要因素。本文主要研究一类RTOS-OSEK操作系统任务上下文切换的改进。针对不同的任务状态，我们采用不同的上下文切换策略来减少上下文切换的平均时间。该方法已在我们的OSEK兼容操作系统smartosek OS中成功实现并进行了评估。

An improved method of task context switching in OSEK operating system

Improving real-time is one of the most essential problems in studies of real-time operating system (RTOS). The time of task context switching is an important factor that affects the real-time of RTOS. This paper concentrates on the improvement of task context switching of one kind of RTOS-OSEK operating system. According to different task states, we apply different context switching strategies to reduce the average time of context switching. This method has been successfully implemented and evaluated in our OSEK compatible operating system-SmartOSEK OS.
