Frame Grabber For The Pci-e Development

With the developing of computer science and video technology, digital image acquisition is widely used in communication and signal processing field. As the foreside of computer video equipment, digital image acquisition card has the task of conversion from analog video signal to digital image. It is significant to design an embedded image acquisition system, which is useful and convenient.In this dissertation, digital image acquisition system's actuality and future are presents at first. Designing an auto-adaptive high resolution image acquisition card is the goal of this project.The basic form of an image acquisition system is FPGA processor, A/D converter, memory, and the PCI/PCI-E brige. In this dissertation, the system design and the chips selection are introduced.The programme in FPGA is very important in the design. This complicated system contains data acquisition module, data storage module and data transimition module. The most important thing is that making these modules work together and cooperatively.Developing the WDM driver is also very important. The driver controlls the acquisition and the data transimition.The dissertation introduces the development of the driver as well as the working flow in detail.Finally, the results of FPGA simulating and system debugging are put forward at the end of this dissertation. And, the development of the image acquision is summerized, as well as the future view.
