摘　　要：随着Linux在嵌入式操作系统领域的广泛应用,改进Linux的性能,使他适用于实时领域成为一个备受关注的研究方向。首先分析了当前Linux在实时系统中的局限性,并讨论了几种改进方法,最后对Linux核心可抢占性的方法提出了改进措施:中断管理进程化。通过中断管理进程化能够有效地改善Linux在实时性能方面的局限性。As the application of Linux to the embedded system is more and more popular, it is regarded as a potential aspect by many users to improve Linux performance to satisfy the real - time requirement. Firstly this article analyzes the limitation of the Linux＇s application to real- time system, then discusses several improved methods, at last, the article gives arise to three method to improve the prempatibility of linux kernel：tasked interrupt hangdling. This method can improve the real -time capabilities of Linux system.
