Abstract
With the electronic technology, multimedia technology munication technology developing, video surveillance system has still been the focus of attention and it is widely used in the industrial, military, civil and other fields. Video monitoring with an intuitive, convenient and abundant information can provide customers with high quality control means. From backward to advanced field monitoring of remote monitoring control, from analog to today's digital surveillance systems, video surveillance technology is being toward work, mobile and intelligent direction.
At the same time, improving the performance of embedded processors and video processing technology, video capture surveillance system is no longer limited to high-performance PC platform. Embedded and portable platform has rapid development.
In this article, the technology has three areas: embedded processor ARM processor technology, digital video chips and video coding standard to achieve control of the digital acquisition and storage systems.
This thesis focuses on video surveillance and video capture hardware of the system studied, ARM processor using the ARM9 series S3C2410 and taking a Linux system with the treatment. The design includes the power circuit design, clock circuit, reset circuit, memory module, JTAG interface, UART serial debug
