摘　　要：针对嵌入式系统应用和开发的需要,提出了在ARM嵌入式平台上移植Linux系统以及动态加载QoS模块的方法.本文在研究了Linux内核与ARM系列处理器工作原理的基础上,移植了Linux系统并设计了适用于互联网通信的QoS模块.测试分析表明,移植后的Linux系统能正常加载QoS模块,并能够良好运行在ARM平台上,证明了所提出方法的有效性.实验结果证明,该方法对其他嵌入式系统和互联网络服务质量的开发有一定的参考价值.To meet the needs of embedded system application and development, method of transporting Linux system and dynamically loading QoS modules on RAM embedded platforms is presented in this paper. On the basis of studying Linux kernel and the working principle of ARM processor, the authors transported Linux system and designed QoS modules which are applied for Internet communications. The testing analysis shows that the embedded Linux system which was get by transporting Linux system and dynamically loading QoS modules can run on ARM platform steadily and load QoS function module normally. Experimental results indicate that the method is effective. It also can be used as the basis of the development of other embedded systems and Internet service quality.
