基于PCIE的雷达数据采集卡驱动程序设计

摘要

PCIE as a new generation of bus technology is widely used in aerospace and industrial control fields because of its high bandwidth,high performance,high scalability,high reliability.Now,with the phenomenon that digital images acquisition are flaky,quiescent and missing in carrier-borne live-fire radar,and under the Windows XP operating system,this paper introduced the function driver development of PEX8311 bridge chip based on DDK driver development tool and WDM model.Driver initialization,data transmission of initialization and ISR interrupt routine are mainly designed in this article,and the driver is successfully applied in a certain type of navigation radar image acquisition card through the DMA transfer mode.The experiment demonstrated the PCIE driver radar acquisition card's transmission rate can reach 200 MB/s.%PCIE作为新一代总线技术,因其高带宽、高性能、高扩展性、高可靠性而广泛应用于航天领域和工业控制领域.针对目前舰载实装雷达数字化图像采集中存在卡顿、停止和局部图像缺失现象,本文基于WDM模型在Windows XP操作系统下,采用DDK的驱动程序开发工具,对PEX8311桥接芯片进行了功能驱动程序的开发.主要对驱动程序的初始化,数据传输的初始化和ISR中断例程进行了自行设计,并通过DMA的传输模式成功应用于某型号导航雷达采集卡中.经实验证明具有该PCIE驱动程序的雷达采集卡传输速率可达到200 MB/s.
