摘要
PCI总线已经成为工业控制计算机中的主流总线结构,文中给出了采用PCI总线的DMA方式来实现大量高速数据捕获,包括DMA数据传输和突发数据传输的实现方法。该方法的驱动程序采用WinDriver驱动开发平台,并借助PCI设备操作函数的动态链接库,使Windows驱动程序的开发更加容易,缩短了驱动程序开发与调试周期,并可方便地应用于其它PCI设备的控制。
PCI bus has become the mainstream of industrial control computer bus architecture.DMA way with PCI bus is adopted to achieve a large number of high-speed data capture,including the implementation method of DMA data transmission and burst data transmission.The driver employs WinDriver drive development platform,and utilizes the dynamic link library of PCI device operations function to make Windows driver development easier.It shortens the driver development and debugging cycles,and can be easily applied to the control to other PCI devices.
