摘要
采用对轻量级图形库 DirectFB封装的方法,基于分层体系结构设计了一个高效且易于开发的嵌入式 GUI系统DfbGUI,并详细介绍了DfbGUI的关键部分封装层的实现.测试结果表明,与现有的嵌入式 GUI系统相比,DfbGUI系统资源占用率低、处理效率高,较适合于嵌入式应用.
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.
