摘　　要：设计了一种基于TCP/IP通信协议、使用以太网控制器芯片W5100与ARM内核芯片AT91SAM7SE实现的数据传输系统。介绍了系统的硬件设计、接口时序以及软件流程。设计提出对W5100与AT91SAM7SE的硬件接口采用直接总线连接模式,软件操作采用直接总线连接模式与间接总线连接模式相混合的方式,以达到高速传输的目的。A data transfer system is introducesd in this paper ,that is based on TCP/IP protocols and using Ethemet controller W5100 and AT91SAMTSE which combines an ARM core. This paper describes the system＇s hardware design, interface timing as well as the software flow. In order to achieve high speed transmission, the interface between W5100 and AT91SAM7SE is direct bus interface mode, and the software operation is based on direct bus interface mode mixed with indirect bus interface mode.

关 键 词：W5100 TCP IP 数据传输
