Based On PCI Bus Video Image Acquisition System Design

Image processing is always an important control engineering research. Along with the computer multi-media and data communication technology, the development of image acquisition and processing of the demand is higher and higher. Take the microcomputer CPU, for the image based on PCI bus in front of a sampling image acquisition system is a kind of high performance and low cost of design scheme.This article is in the full understanding of video image acquisition system on the basis of the development trend of design based on PCI bus video image acquisition system. Using phase lock loop technique based on FPGA, produce pixel clock technology to design collection system logic control and ADC and external memory and PCI bus between controller of sequential coordinate work. Using the PCI bus controller to finish on PCI bus control and data transmission, after work more quickly realized data into system memory. With the emerging technology, make the video image acquisition system design work becomes more convenient and flexible, efficient and reliable, also make the whole system and reduce the cost.
