摘　　要：现场可编程门阵列(FPGA)得到广泛的应用,在当前的背景下,国产FPGA异军突起,有其重要的意义。为了提升国产FPGA的应用水平,其对典型应用的高效支持将显得尤其重要。以装载了国产FPGA的紫光同创的PGL22G-MBG324开发板为基础,基于PANGO-M1软核和定制逻辑来实现传输控制协议/网际协议(TCP/IP)千兆网接口通信系统,在硬件端设计出能灵活适应各种网络传输速率的媒体访问控制器(MAC)和实现与外部物理层(PHY)连接的高速网络接口,在软核端移植了轻量型网络协议(LwIP)协议栈,实现软核与个人计算机(PC)的高效通信。移植作品效果显示,国产FPGA在网络通信上具有高度适应性。Field Programmable Gate Array(FPGA)has been widely used. Under the current background,domestic FPGA has emerged as a new force,which is of great significance. In order to improve the application level of domestic FPGA,its efficient support for typical applications will be particularly important. Based on the PGL22 G-MBG324 development board of Ziguang Tongchuang which is loaded with domestic FPGA,PANGO-M1 soft core and customized logic were used to realize the Transmission Control Protocol/Internet Protocol(TCP/IP)Gigabit network interface communication system. On the hardware side,an Media Access Controller(MAC)that can flexibly adapted to various network transmission rates and a high-speed network interface to realize the connection with the external PHYsical layer(PHY)was designed,and the Light weight Internet Protocol(LwIP)stack was transplanted on the soft core side to realize the efficient communication between the soft core and the Personal Computer(PC). The effect of transplanting works shows that domestic FPGA is highly adaptable in network communication.
