摘要
介绍了基于PX I总线的高速数据采集系统中断处理机制和中断程序的设计以及DMA传输的编程实现,给出了驱动程序设计的关键部分。在W indows 2000操作系统下,该系统可以在64 MB/s的速度下实现无丢失的数据传输存储操作。
Based on PXI local bus, a scheme for data collection system of high rate is presented and the driver development of interrupt operation and DMA programming are discussed. The flow of the driver is presented. Under the OS of Windows 2000, data can be transferred and stored at 64 MB/s without loss through the system.
