| Abstract: | This paper discusses the advantage of 64bit PCI card, introduces the application of the Image Data High Speed Collection PCI Card in Color Image Scanner System, gives the implementation method of the PCI Card, and the key points of PCI driver program in Linux system. This Image Data High Speed Collection PCI Card has higher sample frequency, and higher data transform speed, facilitating the broadband 64bit PCI bus. The application software in the Linux system shows that this PCI card can collect color image data with high reliability, and fulfill the demand of the Linux application software for the Color Image Scanner System. |
