摘要
为了解决图像扫描设备与主机之间海量数据高速传输问题,提出了一种基于FPGA的图像数据采集卡的设计方法。该设计方法对采集卡的原理设计、FPGA的开发以及驱动程序的实现进行了研究;板卡采用了PCI9054接口芯片与主机的PCI总线进行通信;根据采集卡的功能要求,FPGA选择ALTERA公司的EP1C6Q240C8;为保证采集系统实时性的要求,应用WinDriver及其KernelPlugIn技术在操作系统内核态下完成了驱动程序的开发。该采集卡具有DMA传输、可连续采集等特点,目前已成功应用于图像数据的采集。
A new solution of image data acquisition card based on FPGA is introduced,to solve the problem of mass-data high speed transfer between the image scanner and the host computer.The principle design of the card,development of FPGA and the implement of driver program are presented.PCI I/O Accelerator PCI9054 is integrated to communicate with PCI bus of computer.To meet the function requirements,EP1C6Q240C8 is chosen as FPGA.Driver program is developed at the kernel of operating system using WinDriver and Kernel PlugIn technology,which is considered for realtime property of the system.The card has the features of DMA transfer and consecutive sampling.The instrument is now used for sampling of image data.
