【Abstract】 By adopting the method of encapsulating a thin graphics library-DirectFB,this paper designed a new layered-architecture-based embeded GUI system,named DfbGUI. The system DfbGUI is high efficient and easy to be used for developing.And this paper also introduces the implementation of the encapsulation layer that is the key section of this DfbGUI’architecture.The experimental results show that the system DfbGUI employs less system resources and holds more efficient than the current embedded GUI system,so it can been applied to develop a GUI for embedded products.更多还原
