Design of the Video Image Capture Card Based on S3C6410

The receiving and processing system of analog videos is based on the ARM11 S3C6410 processor of SAMSUNG with the video front end chip, TVP5151 of TI, a high-speed analog video receiver chip. Design the corresponding schematic circuit diagram, and the driver of TVP5151 based on Linux is programmed. Realize seamless connection of hardware and software between the TVP5151 and S3C6410 Camera interface. It focuses on the hardware design, corresponding register settings and the progress of programming the device driver. In order to increase the display speed, a memory mapping method is used during the design of the application program. Experimentations indicate that the designed system is stable, of clear images and has strong practical application values.
