摘要
在实时操作系统中,调度策略是直接影响实时性能的主要因素,因此不同种类的任务希望得到相应的调度方法。本文介绍了μC_OS II的任务调度策略,通过分析μC_OS II调度策略中的缺点,提出了一种新的任务调度机制。该机制在保证μC_OS II内核实时性的基础上,使得不同的任务得了到最佳的调度方式。
In real-time operating systems,the scheduling policy is a primary factor that affects the real-time performance. So, different kinds of tasks fit different methods of scheduling. This paper introduces the task scheduling policy based on μC _OS-II . By analyzing the shortcomings of the scheduling policy based on μC _OS-II ,this paper provides a new mechanism of task scheduling. This mechanism can make each task get the optimal scheduling mode on the basis of the real-time kernel.
