Design On Video Compression System With The ARM9

In recent years, with the rapid development of the embedded systems and image processing technology, it is possible to carry out the video surveillance system which based on the embedded. And the research of data communications has become a hotspot of development to combine the embedded and video and This article introduced the standard of the digital video image compression and JPEG compression algorithm, by analyzing the requirements of the system, selected the chip, completed the design of video image compression system which based on ARM9-based.First of all, in nowadays multi-compression technology, which according to the needs of the designed system, the paper chose the design of JPEG compression standard, and made a technical presentation. Then put forward the hardware diagram and software flow diagram. Next this article introduced the specific hardware platform and the design of software. Hardware platform introduced a video capture unit of video capture chip SAA7111A, the video compression chip in the video compression unit ZR36060, the microprocessor control unit S3C2440, and the power circuit, reset circuit, the circuit of switch dial code, the Flash memory circuit, the JTAG debug circuit, the UART interface and other design of features hardware modules. In the software design, Liunx operating system and the Boot Loader briefly, and introduced the design of the SA7111A driver the initialization of the configuration ZR36060, the design of the Nand Flash programming and the desing of the serial communication primarily. Finally, analysis the image system by the image test procedure.As a result of embedded, the design of this article has the advantages of the small system the flexible operation, can be applied to a variety of occasions, and provide a viable technology of building the video capture system.
