摘要
文章针对嵌入式以太网接口设计方案,介绍了DM9000A的功能原理并给出了系统的硬件框图;讨论了接口软件部分,重点论述了底层数据的处理过程和通过TCP/IP上层协议的数据收发过程;完成了一个嵌入式以太网接口的设计,实现了数据的传输,并且数据的正确性得到保证。
To design an embedded Ethernet interface,the functions and principles of DM9000A chip is introduced and the hardware block diagram of the system is put forward.For the software part,the processing of data on the bottom and the sending and receiving of data through the TCP/IP upper layer protocol are discussed.Based on this design of embedded Ethernet network interface,the data transmission is achieved and the accuracy of the data ensured.
