摘　　要：面对越来越多的FPGA网络通讯方式,提出了一种以Xilinx Spartan-3E开发板为目标器件,基于Xilinx MicroBlaze微处理器软核,与相关外设IP核一起构建基于片上可编程系统的网络应用平台,通过移植开源TCP/IP协议栈LwIP,提出了一种不需要操作系统的LwIP协议栈的高效工作模式,实现FPGA与以太网的通讯。设计给出了系统的软硬件平台设计,以及对整体设计的实验验证。Faced with a growing number of FPGA network communication, we propose a network application platform based on programmable chip （SOPC） using a target device of Xilinx Spartan -3E development board , based on Xilinx MicroBlaze microprocessor soft - core , built together with the related peripheral IP core. FPGA and Ethemet communications through transplant open source TCP/IP protocol stack LwIP. Proposed a LwIP ef- ficient operating mode does not require operating system. The paper describes the design of the system＇s hard- ware and software platform , and the experimental validation of the designed system.
