A Graphic User Interface And Browser System For An Embedded Real-time Operation System

With the development of information Technology and Internet, embedded real-time system has been more and more widely used in electrical and electronic products and communication fields. And as embedded products were commercialized, embedded graphic user interface and embedded browser have gradually become indivisible parts of a mature embedded operation system.We have considered generally in module partition and system structure design of the Embedded real-time graphic user interface ARTs-GUI, It is achieved as a single-window mechanism to adapt the high capability requirement and equipment limit. We adopted layered module scheme and designed a hardware abstract layer to make the system to be easiler to be transplanted and reduced. We provide multi-driver for multiplicate device, offer multi-layer interface including graphic engine interface and window interface, and use message mechanism and recall function correspond tasks among modules and built foundation for achieving multi-window function.The tactics of parse and display web pages of existing browsers are implemented divergent widely. We proposed and implemented web page division mechanism after analysis and comparing shortage and merit of several dominating mechanism roundly, and store displaying information of web page blocks by a bintree. In addition, In order to improve further the speed and reduce the response time of the browser, we assembled several modules such as syntax parsing, semantic parsing and page displaying to one module ,which increase further the browser's efficiency its response speed. Finally, We put forward rectify mistake design and page matching technology to improve system's haleness and its practicality.
