As mankind enters the PC era, embedded technology has been rapid development and wide application, embedded systems have become the most popular, the most promising IT applications. Including mobile phones, electronic dictionaries, video phone, digital camera (DC), digital video cameras (DV), U-Disk, STB (Set Top Box), high-definition TV (HDTV), video games, smart toys, switches, routers, CNC equipment or instrumentation, automotive electronics, appliance control systems, medical equipment, aerospace equipment, etc. are typical embedded system. This paper presents a design and implementation of the program, the player has a VGA screen interface, but also has the function of network control based on the embedded LCD player. First, This article detailed analysis of the embedded architecture, transplantation of embedded Linux operating system in the ARM9 microprocessor, including the cross compiler built environment, the boot loader application, transplant embedded Linux kernel and root file system,and embedded Linux to S3C2440 development board transplantation. Due to hardware constraints of embedded systems, commonly used in PCs graphical user interface (GUI) system is not suitable for running on it. To this end, we selected Qtopia-2.2.
