嵌入式Linux操作系统的实时性能分析与改进

随着嵌入式应用越来越广泛，嵌入式操作系统受到极大的重视。传统的嵌入式实时操作系统，由于各种原因不能满足我国日益广泛的需求，快速开发一个价格低廉、效率较高的嵌入式实时操作系统迫切需要。利用现有的Linux操作系统进行改造，是其中很好的一个方法，然而Linux是一个通用的操作系统，在实时性能上还不能够满足需要，对Linux的实时性能进行了分析，并提出了改进Linux实时性能的方法。

Analysis and Improvement of the Real-time Performance of EmbeddedLinux Operation System

With the increasing demand on embedded computing devices, embedded real-time operation system has been given more attention. For the high cost or inefficiency of traditional real-time operational system, quickly building a low-cost effective embedded operational system is far more important. It' s popular to reconstruct a real-time operation system from the existing Linux operation system. In this paper, the real-time performance of Linux has been analyzed and ways are provided to improve the real-time performance.
