摘　　要：在研究目前图像数据传输方案的基础上,提出了一种可实现长距离、无延时图像数据传输显示的优化方案。该方案基于FPGA技术、PCI接口协议和EthernetMII接口协议,使用自定制PCI接口板卡作为PC机与大屏间的数据传输硬件核心。给出了系统架构、PCI接口卡的硬板设计、FPGA设计、驱动程序开发和三级验证手段,设计灵活性大,扩展性强,系统能满足高传输速度、高清晰度和高稳定性的需要。Through research present-day image data transferring system, a kind of optimized method is put forward to realize long-dis tance, no-delay transferring and display of image data. Based on FPGA technology, protocol of PCI interface and Ethernet MII, a customizable PCI interface card is designed as core of hardware which connects PC and LED large-screen. System architecture, PCB design of PCI interface card, FPGA design, driver development and three-grade verification are given. The system can be designed flexibly and scalably. The requirement of high-speed, high-definition and high-stability are satisfied.
