介绍了一种基于CPCI总线的高速数据采集卡硬件及其WDM驱动程序设计方法,详细说明了计算机通过驱动程序与数据采集卡硬件进行高速数据交换的方法,利用DriverWorks完成了满足高速数据传输要求的WDM驱动程序设计,实现了数据采集卡与主机内存之间数据传输的DMA方法。
A high-speed data acquisition card hardware based on CPCI bus and its WDM driver design method are introduced. The method of high-speed data exchange between computer and driver by data acquisition card hardware is described in detail. DriverWorks is used to meet the requirements of high-speed data transmission WDM driver design, to achieve the data acquisition card and host memory data transfer DMA method.
