【摘要】 基于图形用户界面(GUI)的嵌入式应用越来越广泛。常见的通用GUI产品往往尺寸大,开发细节多,不适合嵌入式场合的成本和开发周期要求。文中提出了一种GUI系统结构简洁,相对现有GUI产品尺寸更小,同时由于采用了面向对象的模块化设计与仿真器技术,开发更为方便快捷。以会议电视终端为例,介绍了该系统的实现。在会议电视终端的应用中,该系统小巧灵活,同时开发过程只需要很短的时间,有效的降低了产品成本和开发成本。更多还原

【Abstract】 GUI(Graphic User Interface) based embedded applications are now widely in use.Common GUI products are usually large in size and complicated in detail.An embedded GUI system,which is more lightly weighted than most of current GUI products,was proposed in this paper.Due to adopting both object oriented modularized designing and a well-designed simulator,it is more convenient to develop this system.Its implementation in Video Conference Terminals was also introduced.In this implementation,this system took small memory size,and cost significantly short development time.It greatly reduced the cost of both product hardware and development labor.更多还原
