摘　　要：红外图像获取与处理系统中需要编写高效的图像采集电路的设备驱动程序。文中介绍了一种针对这类数据采集电路的外设部件互连 (PCI)设备驱动程序的设计方法 ,着重讨论了硬件访问、中断处理和直接存储器存取 (DMA)传输等 3个方面的问题 ,并给出了相应的解决方案。详细叙述了利用DriverStudio软件开发Windows 2 0 0 0系统下WDM(WindowsDriverModel)设备驱动程序的流程 。In an infrared image acquiring and processing system, a highly efficient drive program of image acquiring circuit is very essential. In this paper, we introduce a design method which is aimed at this kind of acquiring circuit based on PCI bus. Three questions are emphatically discussed, namely hardware access, interrupt processing and DMA transmission. Then we provide the corresponding solution. The program flow of WDM device driver in Windows 2000 using Driver Studio software is described in detail and finally communications between hardware and application software is realized.
