摘　　要：信息化条件下的联合一体化战争中,实时采集到的海量数据对上位机和采集卡间的数据传输速率提出了更高的要求。为解决采集卡与上位机之间的海量数据传输问题,结合Arria 10GX1150器件,实现了一种基于PCIe 3.0的驱动与上位机软件的开发方案。对使用WinDriver开发设备驱动和DMA传输方法进行了介绍,并设计和实现了一种使用乒乓操作优化DMA传输链路的方法。实验结果表明,在PCIe 3.0链路下,数据采集速度可达到200 MB/s,而且稳定高效,能够满足高速数据采集要求。Under the information condition of the joint integration war,the massive data collected in real time requires higher data transmission rate between the host computer and the acquisition card.In order to solve this problem,this program applies Arria 10 GX1150 device with its PCIe 3.0 driver and host computer software to realize a development scheme.In this paper,the WinDriver development device driver and DMA transfer method are introduced,and designs and implements a method to optimize DMA transfer link by ping-pong operation.The experimental results show that,the data acquisition speed can reach 200 MB/s under the PCIe 3.0 link,which can meet the requirements of high speed data acquisition.
