摘要
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。
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.
