摘　　要：本文针对Linux内核实时性及其应用领域的需求做了分析研究，并对Linux2．6内核源代码进行了分析。在此基础上，针对2．6内核实时性的不足提出了改进方案，在中断及调度机制方面建立新的中断体系及任务模型，并进行了试验调试。测试结果表明，改进后的Linux内核的响应速度显著得到了提高。In this paper, the real-time of Linux kernel and the requirements of its application fields are analyzed and researched and the source code of Linux 2.6 kernel is analyzed. On this basis, aiming at the shortage of real-time of Linux 2.6 kernel, an im- proved scheme is proposed, and the new interrupt system and the task model are established and furthermore, the experiment and debugging are completed. The test result indicates that the response speed of the improved Linux kernel is notably enhanced.
