The Design and Implementation of Embedded GUI System

Embedded products have features of few resources and large diversity, which determine the software running on them has a peculiar specificity. As the Consumer Embedded Products, GUI(Graphical User Interface) has a very important function, and it is the essential embedded software in embedded applications, the embedded GUI system and traditional GUI system is radically different, so the design of it has a high research value. At present, the majority of embedded products adopt the public-mode schemes to design GUI system. Besides poor appearance and slow-response, it can not add or update the later required function modules. To solve these problems, with the analysis GUI system and embedded OS, this article proposes a new design idea and method of embedded GUI system. The system framework is designed as the nimble state machine and pasting-graphics method is adopted. And finally, the practical application example of MP4 system proves the feasibility of the new design idea.
