Research And Application Of Multimedia Information Terminal Based On Embedded Linux

With the quick development of Informaiton Technology, the research and development of embedded system has to be one of the hotest topic of science and technology gradually, and Linux has to be the major technology of embedded operation system with it's particular advantages. To develop the embedded Linux , the study shoud be emphasize on the software and hardware support. Aiming at the application program system integration is the main part in the software, and for the hardware the main point is it's kernel configuration and compiling for different hardware platform.The paper begins with the analysis of embedded system developing , and educe the particular advantages of adoping Linux to develop the embedded system. Then with the introduction of an embedded multimedia information terminal based on Linux opration system, to talk about the developing flow and method of embedded system in detail. The aspect of cross-compiling environment building, XScale processor selection, embedded Linux operation transplanting, device drivers analysis, Qt/embedded GUI realizing, Qtopia environment building, image capture and network browser Konqueror/embedded are concretely analyzed and dissertated in the paper.At last , expectation are proposed for further developing, it has great value and extensive practical value in embedded Linux system.
