Linux实时性改造技术研究

对Linux实时特性作了讨论，指出造成实时性差的原因，阐述了实现Linux实时性改造的各种不同方法及其优缺点。详细介绍了为保留Linux原有的丰富功能，同时使其作为一个基本内核与实时内核共享CPU所采用的虚拟机技术，设计实现了具有双内核的实时操作系统，提高了Linux实时性能，使其可用于软实时的应用场合。结果表明该改进方法是有效的。

The Reserch for Improvement on Real-time Performance of Linux

Some analyses on real-time characteristic of Linux are made,and points out causation resulted at weak real-time performance,introduces different methods for improvement on real-time performance of Linux,advantage and disadvantage of them, detailedly describes technique of virtual-machine to reserve intrinsic function of Linux and share CPU with real-time kernel, realized real-time system having double-kernels, improves real-time performance of Linux and makes it practicable in soft real-time environments. The result shows that the solution is effective.
