基于FPGA的千兆以太网终端显示系统的设计

VGA（视频图像阵列）作为一种标准的显示接口得到广泛应用；千兆以太网具有传输速度快、传输距离远、稳定可靠等优点，是当前嵌入式系统的应用热点；FPGA拥有丰富的逻辑和光脚资源，常用于高速数据处理和通信的嵌入式系统。文中结合以上三点，介绍了基于FPGA的千兆以太网终端显示系统的设计。通过对该系统方案进行分析，将设计分为3个模块：数据包接收及解析模块、双口RAM缓存模块和VGA控制器模块。文中详细介绍了这3个模块的设计方法，并在此技术上实现了3个模块协同工作完成整个系统的功能，并给出了系统仿真结果和显示效果。

Design of Gigabit Ethernet Terminal Display System Based on FPGA

VGA （ Video Graphics Array） is widely used as a standard display interface. Gigabit Ethernet,which has advantages of high-speed transmission,long-distance transmission,high stability and reliability,plays an important role in the current embedded systems. FP-GA has rich logic and pins resources,which is often used in high-speed data processing and embedded communication systems. Based on the above three points,introduce the gigabit Ethernet terminal display system design based on FPGA. Through the analysis of the system scheme,the design is divided into three modules：packet receiving and parsing module,dual port RAM cache module and VGA controller module. Introduce in detail the three module design method,and realize the three modules in this technology to work together to complete the function of the whole system,and the system simulation results and display effect is given.
