摘 要: 综合PCI、DDR、FPGA、光纤等技术,设计了一款远程高速CCD图像采集卡。采集卡用光纤传输信号,并使用DDR SDRAM作为数据缓存,采用EP2C35F484C8芯片实现采集卡的逻辑控制以及DDR的控制器,采用PCI9054桥接芯片实现PCI接口。以Numega公司的DriverWorks作为开发工具开发了基于Windows下的WDM模型的系统驱动程序,用VC6.0开发了基于Windows平台的可视化应用程序。 A card for gathering CCD images remotely based on PCI DDR FPGA and FIBER technology is designed. Fiber is used as the signal transmitting method, DDR SDRAM is used as the data buffer and EP2C35F484C8 is used for implementing the system logic control and as the DDR controller in the gathering system. The system driver is developed based on the WDM model of Windows using the DriverWorks of Numega company. The system application programme is developed using VC6.0.
