The embedded systems and embedded GUI system are simple introduced in this paper,the necessity that develop the embedded GUI systems platform is also described in this paper. The three common embedded GUI system (Micro windows, Mini and QT GUI) are detailed introducted ,including design structure and the use of the advantages. Comprehensive comparison of the Embedded GUI several ways,combining the characteristics of embedded systems,focus on the use of Bresenham algorithm mapping images.
