基于PCI总线的高速数据采集卡的设计与实现

Design and Implementation of High-speed Data Acquisition Card Based on PCI Bus

随着图形图像技术的不断发展 ,数据采集技术也越来越受到人们的关注。为了解决特定外部设备与主机之间的海量数据传输问题 ,该文提出了一种基于PCI的高速数据采集卡的实现方案 ,讨论了采集卡硬件设计中的一些关键问题 ,详述了如何对采集卡内部控制逻辑进行设计 ,并给出了基于WDM的设备驱动程序的设计方法。

With the development of graphics and image technologies, people have pay more attention to the technology of data acquisition. To solve the problem of mass-data transfer between the specified peripheral equipment and the host computer, this paper brings forward an implementation scheme of high-speed data acquisition card based on PCI bus, discusses some key problems of hardware design, describes how to design the control logic in the card, and then gives the design method of device driver based on WDM.
