摘　　要：基于ARM7TIMD内核的处理器S3C44B0X和以太网控制器RTL8019AS,设计了一种以太网接口,介绍了以太网的帧结构、SC44B0X的性能及RTL8019AS的逻辑结构和工作原理,着重基于硬件层设计了以太网硬件接口和驱动程序,实现嵌入式以太网的数据传输。它适用于中小型嵌入式系统的网络化,可满足数据采集和自动化控制等方面的需要。Using the microprocessor S3C44BOX 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 S3C44BOX 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.
