Abstract


With the development of digital technique, the video technology has become into digital technology from analog, which is an irresistible trend. And with the development of large-scale integrated circuits, it has been possible to use the digital image compression technology to achieve high compression ratio and high-quality digital image recording system. The method of digital recording can store the high-quality compressed digital image in the large capacity memory, increase the storage time and transmit quickly through computer networks. On this basis, to fulfill the digital screen acquisition and storage by using embedded system could not only acquire MPEG4 screen image with high quality and low bits rate, but also have advantages of small-volume, low-power, high-reliability low-price and etc, it is the ideal way to resolve the problem of how to decrease the costs of screen record storage system.The aim of this paper is focus on the design of digital screen acquisition and storage on the basis of embedded system, and designing screen acquisition and storage system with high-quality, small-volume, low-power and high-reliability according to the characteristic of embedded system’s own features. After summarize the basic functions and features of embedded system, it is decided that this system are composed of control module, acquisition compression module, compression coding module and storage module, which the fulfill of control module is by using LPC2210 produced by PHILIPS company’s ARM7 chip, acquisition compression module is by using CCD camera, screen decoding chip is by using SAA7111, compression coding chip is by using IME6400, and the storage module is by using IDE interface of LPC2210 and electrical plant. On the basis of comparing advantages and disadvantages of many operating systems, choose reasonably embedded Linux system as the operating system of embedded platform, and transplant it in the hardware platform that on the basis of ARM7TDMI-S processor, constructed the development environment of embedded Linux system. According to the feature of Linux driver program architecture, introducing the principle of how to go on with module driver and download reappear as well as the creation of program under the Linux system, and part of the source code are shown in the paper.
