Linux周期性实时任务的开发

Programming of periodic real-time task in Linux

Linux正大步进入实时控制领域,但是Linux并没有提供对周期性实时任务的直接支持。如何在Linux下进行周期性实时任务的开发是一个难题。分析了周期性实时任务的开发内容,从实时任务的特性设置、任务的周期实现到任务的具体功能实现,并给出了关键代码。

The Linux is entering the field of the real-time control. But there are not direct interfaces with the periodic real-time task. How to program the periodic real-time task in Linux is a problem, The development of the periodic real-time task includes setting its scheduling nature, period and function. The key codes of the sample are also presented.
