Dynamic Ticking : the Practical Implementation Method for the Real-time Task Scheduling

In this paper a new method dynamic ticking is proposed to control tasks more e ciently on real time operating systems It makes higher priority tasks run more e ciently by preventing useless occurrences of the timer interrupt request Operation of dynamic ticking is presented and several issues are discussed to be adopted at previous systems To estimate the performance the schedulability is analyzed The enhancement of the performance mainly depends on the number of preemption which is closely related to the timer interrupt An implementation model is introduced to show the simplicity of the implementation Dynamic ticking improves the performance of real time system which controls tasks in detail
