摘要
介绍了一种基于ARM 9的嵌入式以太网的设计方案。基于ARM内核微处理器S3C2410的功能特点及其外扩组成部分,分析了以太网控制器芯片RTL8019AS的性能以及与S3C2410的接口。在软件设计上,分析了BootLoader的作用,介绍了L inux的移植,并给出了通信程序的流程图,实现了嵌入式以太网的数据传输。
In this paper, a solution was proposed for embedded EtherNet based on ARM9. Firstly, the function and character as well as the expansion of the microprocessor S3C2410 were introduced, then the character of RTL8019AS and the interface with S3C2410 were analyzed. From the software, the function of BootLoader and transplant of Linux were expanded in detail. Lastly, the flow of the communication was given. The transport of the data was realized.
