摘要
在嵌入式系统中,可以利用TCP/IP协议,成功的实现双机网络互连,既提高了数据传输的速度,又保证了数据传输的正确性,同时也扩展了数据传输的有效半径。该文介绍TCP/IP通信模块的硬件构成、功能和以太网接口芯片的驱动方式,完成了以太网硬件电路和驱动的设计。
The connection of double computer and networks is successfully accomplished based on TCP/IP protocols in the embedded system, which can not only raise the speed and reliability of data transmission, but also expand the effective radius of the data transmission. The paper presents the hardware framework and function of TCP/IP communication module and the driving mode of tbe chip for Ethernet interface, and the designs of the Ethernet hardware circuit and driver program are also completed.
