摘要
嵌入式技术在以太网中的应用是当前的研究热点之一。提出了一款基于TCP/IP协议栈的嵌入式以太网终端的设计方案。该方案给出了ARM内核的微处理器S3C44B0X和以太网控制器芯片RTL8019AS的接口电路以及嵌入式TCP/IP栈和μC/OS-Ⅱ实时操作系统的核移植的设计思想和具体开发流程。该方案性价比较高,适用于通信速率要求不高的家庭自动化设备和工控场合。
The Embedded technology applications in the field of Ethernet are becoming one very important subject. This paper presents one scheme of embedded Ethernet network terminals based on TCP/lP protocol stacks. The hardware institution for the interface circuit between the microprocessor S3C44BOX with ARM kernel and the Ethernet controlled chip RTL8019AS is designed. About the software, the designing idea and detailed developing process of embedded TCP/lP Protocol stacks and the core transplanting of the real-time operating system μC/OS- II are introduced. This kind of embedded Ethernet network terminals has high performance price ratio. It is expected to use for home automatic devices or industrial control devices with low needs of communication speed.
