Abstract :
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.
