The design of image acquisition system based on ARM

In recent years, with the rapid development of the computer technology and communication technology, miniaturization and specialization have become the main developing trend. At the same time, embedded products have turned into the main stream of information industry. The technique of embedded system has become the most popular technique in electronic realm currently, which has already been broadly applied in the areas such as national military defense, consume electronics, network correspondence and industry control. This paper proposes a video capturing and processing method based on a 32-bit CPU after an overview of the development of video signal capturing and processing technology. The internal rich interface resources of embedded microprocessor chip S3C2410 of ARM9 have been fully used in this system. The system is based on the Linux operating system and uses hardware and software co-design approach to complete the design to make it more integrated. In addition, the system is compact, and operates without PC intervention, which makes the configuration more flexible and the display interface more friendly.
