Embedded Gui Research And Implementation

In post-PC age, mobile-computing, basic network equipments, electronic commerce and the reuse of software are regarded as the four most future-effecting techniques. Mobile-commerce has become the most forward-looking new topic now a day. The digitization and networking has become the developing directions of electrical appliances. As the core technique of mobile-computing, mobile-commerce and informative electrical appliances, embedded database has become the hot spot of study in the field of database technology.Since embedded GUI system often appears as the applications of embedded system, firstly the particularity of embedded systems, compared with classical computer systems, is thoroughly studied in the matter of hardware, operating system and applications. Then the concept characteristic and popular system frame of embedded GUI systems are introduced. Today, with then rapid progress of embedded GUI technology, all kinds of embedded GUI products have become more and more popular in native and oversea appliance fields. In this paper, the system frame and functions of some of the most popular embedded GUI systems, such as X Windows,MicroWindows, OpenGUI, QT/Embedded etc., are discussed.The author of this paper took part in the development of the embedded GUI system based on one kind of PDA, and then finished this paper. In this paper, the functions, capability, system structure of this embedded GUI system and the reality of the system are pinpointed.
