| 摘 要： | Linux属于通用的分时操作系统，因此将它应用于实时系统领域必然存在一些不确定性问题，如内核不可抢占、时钟粒度粗糙、缺乏有效的实时调度策略等。为了解决这些问题，出现了一些如RT-Linux、Kurt-Linux、Hardhat-Linux等Linux实时性研究项目。文章在对Linux实时性研究的基础上，介绍了中断进程化的研究工作和实验结果。结果表明这种改进是显著的，较大地减少了内核的不确定延迟。

| Abstract: | The Linux kernel techniques, such as non-interruptible kernel, coarse-grained time mechanism and lack of effective real-time scheduler etc., can’t well support the confirmability which is the basic characteristic of real-time operating system. Much research has been done on the real-time Linux in the world. In this paper, the shortcomings of Linux kernel when applied to real-time system and the relevant solutions implemented in some famous Linux projects, including RT-Linux, Kurt-Linux, and Hardhat-Linux, are introduced. Research on implementing interrupt in process is introduced and the final experiment shows that the research is effective and significant. |
