Linux与VxWorks的任务调度研究及应用

Research and Application of Task Scheduling Between Linux and VxWorks

任务调度作为操作系统的核心之一,不同操作系统的重要区分就是调度的差异性,因此,对其进行研究有重要意义。笔者简单比较了嵌入式实时系统Vx Works和Linux在调度机制方面的差异,主要就调度策略、调度算法原理作了分析与比较。调度机制的分析与研究,对实际项目中进行的Vx Works到Linux移植,起到了较为关键的指导作用。

Task scheduling is one of the core of operating system,and the important distinction of different operating systems is the difference of scheduling.Therefore,it is of great significance to research it.In this paper,the differences between Vx Works and Linux in the scheduling mechanism are compared,and the scheduling strategy and the principle of scheduling algorithm are analyzed and compared.Through the analysis and research of the scheduling mechanism,it plays a key role in guiding Vx Works to Linux transplantation in actual projects.
