摘要
航天测控系统面临着操作系统升级的问题,这就需要为数字基带板开发基于64位操作系统的设备驱动程序。针对这种需求,研究了Windows操作系统下驱动程序基础(Windows Driver Fundation,WDF)驱动程序的工作机制,采用WDF程序框架设计了基带设备板卡设备驱动程序,并设计了相应的应用程序编程接口(Application Programming Interface,API)和测试程序。通过对设备驱动程序及数字基带板的测试,结果表明其功能得以实现,双通道数据接收能够在40 Mbps速率下长时间稳定地工作。
Space TT＆C systems has to confront the problem of operating system upgrading.And there is a demand to develop the device driver programs for Digital Baseband Card based on 64 bits Windows operating system.For this case, we have studied the working principle of device driver programs based on WDF. With this WDF frame, the device driver programs of digital baseband card is designed.Also, the application programming interface and test programs have been designed and developed. Some tests have been performed for the device driver programs. The result demonstrates that it can meet the requirement in function. The data transfer rate using DMA dual-channel reaches 40 Mbps.And it works well continuously for long time.
