TMS320C6455 PCI协处理卡WDM驱动程序设计

WDM Driver Design of PCI Co-processing Card for TMS320C6455

在高速数据传输系统中基于PCI总线的PCI设备得到广泛应用。针对基于TI公司的高端DSP芯片TMS320C6455的PCI协处理卡,详细介绍了板卡的PCI接口特点,给出了在Windows XP系统下使用DriverWorks工具开发WDM驱动程序的方法,并进一步设计了该协处理卡的驱动程序。该方法简单灵活,开发周期短。通过在对规划空间和实时性有着要求较高要求的航迹规划系统的实验表明,实现了上位机与板卡之间的数据高速传输,从而进一步验证了所设计驱动程序的实用性和稳定性。

The PCI device was widely applied to speed up the data transmission in the high-speed system.In accordance with the PCI co-processing card based on TI＇s high-end DSP chip TMS320C6455,the PCI interface of the card is introduced,the method of developing WDM（Windows Driver Model） device driver program for Windows XP based on DriverWorks is designed in detail,which is flexible and can shorten the period of development,and the corresponding device driver is designed.According to the experiment in route planning system,the data transmission through the PCI interface between the host computer and the co-processing card is achieved successfully.The results show that the device driver performs well and stably.
