Use the PXA270CPU as development platform, and adopt the ZVPort of SM502 to realize the SAA7111 video collection driver. Introduce the system hardware and SAA7111 driver design. Develop the bottom driver and application program according to V41 standard. Based on design video equipment entity and example, introduce the response function, communication function between applied layer and bottom layer, image interception function, realize the video collection. The research can give reference to compiling Linux driver program.
