基于FPGA的嵌入式三态以太网设计

Design of Embedded Tri-Mode Ethernet Based on FPGA

提出了一种基于FPGA实现嵌入式三态(10MB/100MB/1 000MB)以太网的设计方案,分别从硬件和软件方面介绍了使用FPGA进行嵌入式系统设计的方法,编写了一个控制系统进行10MB/100MB/1 000MB自切换程序,并在工程中得以实现。

Based on the development of access convergence router （ACR）of National 863 Plan, this article puts forward a scheme using FPGA to implement the design of embedded Tri-mode Ethernet（10MB/100MB/1 000MB）, introduces a way of using FPGA to design embedded hardware and software system, and programs a controlling system for auto change among 10MB/100MB/1 000MB . Such design is realized in project.
