一种嵌入式GUI中间件的设计与实现

Design and Implementation of Embedded GUI Middle-ware

鉴于当前嵌入式GUI系统支持库体积庞大、结构复杂和难于裁剪的缺点,引入软件设计中常用的中间件思想,结合嵌入式产品的实际,提出了一种新的嵌入式GUI的设计方案。该嵌入式GUI中间件采用基于POSIX的多线程技术、模块化设计,结构层次清晰,系统实时性好,接口丰富便于功能扩展。该嵌入式GUI中间件目前已成功应用在卫星罗经仪设备中,取得了良好的效果。

The present embedded GUI system supported library is relatively oversized,complicated and difficult to be configured.Owing to the above weaknesses and the characteristics of the embedded product,a new embedded GUI system is developed based on common middleware application to software design.The new embedded GUI middleware adopts POSIX-based multi-thread technology and modularization design;it is characterized as distinctive structure,real-time performance and sufficient interfaces.This new embedded GUI middleware is successfully applied into satellite compass with good effect.
