| 摘 要： | 针对当前嵌入式Linux系统调度策略都比较单调,可扩展性不高,文章提出在Linux内核的调度机制中增加面向应用调度框架的方法。为了提高嵌入式Linux的实时性,文章借鉴了RT-Linux软中断模拟的思想,并且借鉴了提高内核可抢占性方法。

| Abstract: | Aiming at such characteristic of current embedded Linux systems as monotonous dispatching and poor sealability,an application oriented dispatching framework is presented and integrated to Linux kernel. Furthermore a method is proposed to improve the kernel preemption of the embedded Linux system.And part of RT-Linux functions are designed and realized. |

| Keywords: | embedded Linux,real-time process dispatching application oriented dispatching framework |
