一种支持多任务桌面环境的嵌入式系统解决方案

摘要

无论是在个人消费电子,还是在车载娱乐系统中,对支持多任务的嵌入式桌面环境的需求越来越迫切.友好的多任务支持为用户提供易用、方便的操作体验.一个健壮的嵌入式生态系统不仅要为用户的日常应用提供基本的桌面功能和应用,还要为开发者提供为该系统编写应用所需的工具和文档.通过守护线程和知名管道机制实现支持多任务的嵌入式桌面系统,并介绍了交互平台开发包的搭建.%No matter personal consumer electronic products,or automobiles entertainment systems, they all cry for the desktop environment supporting multitask. User-friendly multitask support brings easy and convenient experience. A strong embedded ecosystem should provide basic desktop functions and applications for daily needs as well as tools and documentation for developers to write stand-alone applications for the system. With Daemon thread and well-known Pipe mechanism,a desktop environment supporting multitasks was implemented,and the paper introduced a method to develop the SDK for programmers.
