Abstract
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.
