Abstract

Using the microprocessor S3C44B0X with ARM7TDMI kernel and the Ethernet controller RTL8019AS,it designs a new embedded Ethernet interface.Firstly,it gives the frame structure of Ethernet,then it introduces the performance of S3C44B0X and the logic configuration and working principle of RTL8019AS.It also designs the hardware interface and driver program.Finally,it realizes the data transmission of the embedded Ethernet.The design can be applied in the medium or miniature embedded network,satisfy the needs of data collection and auto-control.
