摘要
针对自主设计的基于PCI-E总线高速数据传输卡设备,在64位Windows系统下采用WDM驱动模式设计实现该设备驱动程序。介绍了WDM驱动程序开发过程,主要包括硬件访问、DMA高速数据传输和MSI中断等内容。并对所设计驱动程序进行测试验证,结果表明,该驱动程序具有较高的传输效率和可靠性,可应用于高速数据传输卡设备,且该驱动程序也可移植到其他类似的数据传输设备中。
A high-speed data transmission card device based on the PCI-E bus is designed with the device driver implemented using WDM driver designs in the 64-bit Windows system. The development of WDM driver is introduced in detail, including acquisition of hardware resources, DMA high-speed data transmission, and MSI interrupt. Tests show that the driver with high transmission efficiency and reliability can be applied to high-speed data transmission card device, and that the driver can be transplanted into other similar data transmission devices.
