基于单芯片的高速嵌入式以太网接口设计

Design of high speed embedded Ethernet interface based on single chip

提出了一种单芯片设计方案,解决了在低速嵌入式系统中实现高速网络通信的接口问题。采用带硬件TOE功能的网络微控制器AX11015,融合了小型嵌入式TCP/IP协议栈uIP 0.9,实现了低速嵌入式系统的高速网络通信。实验结果表明,接口模块可以实现UDP数据传输达到20子Mbps,方便接入其它系统中,并已在网络LED大屏幕中得以应用。

A design of embedded Ethemet interface which realized high speed network communication on low speed embedded system based on single chip is proposed. Adopted the embedded micro-controller AX 11015 which has hardware TOE and combined the embedded TCP/IP stack ofuIP 0.9 realized the function. Experiment results indicate that the interface＇s throughput in UDP protocol can reach to 20 Mbps. It＇s easy to be used in other embedded system, and has been applied in net LED screen project.
