| Abstract: | Design of device driver for PCI cards based on WDM is the critical problem for constructing video acquisition system in Windows. WDM model and its working mechanism are analyzed. The key issues of developing general PCI device driver are discussed. Based on the video acquisition card, the device driver is developed. After debugging, the card can meet requirements of real-time acquisition of video image with steady performance, and has been applied to studio system. |
