Compared with 2.4 version kernel, 2.6 has been improved in real-time performance by adopting some new technologies, such as preemptible kernel, new o (1) schedule algorithm etc.

相比2.4内核，2.6采用了一些新技术使得实时性有了很大提高，如可抢占式内核、新的O(1)调度算法等。

Secondly, the heuristic algorithm proposed is used to build FF schedule time list in order to meet the requirement of real-time communication of all remote periodic messages.

其次，提出了基于启发式的FF调度时间表的构建算法，以保证远程周期信息实时通信的要求。

Third, supporting real-time thread in the new schedule algorithm. Next, analyze the Linux kernel source code.

其中主要分析了与调度程序紧密相关的部分代码模块。
