MeeGo Architecture
0 likes1,579 views
MeeGo is an open source mobile operating system that is developed collaboratively by Nokia and Intel. It uses a Linux kernel and supports multiple chip architectures and user experience frameworks. The key components of the MeeGo architecture include the Linux kernel, OS base services, middleware services, and the MeeGo API. MeeGo aims to support handsets initially through the integration of technologies from Maemo and Moblin. The N900 will serve as a reference platform for the MeeGo 1.1 release and will utilize the MeeGo kernel, touch UI framework, and Qt mobility APIs to provide the initial user experience.

- 30. Q & A
- 31. 事前質問 MeeGo 独自のリッチ UI 層は不要であるのでこれを 利用せず、 GTK/GDK/etc... などの、旧来の Linux ア プリ構築の階層を用いてアプリケーションを構築す るような、すなわち、単に旧来の組み込み LinuxOS の代換として MeeGo を利用するようなアプローチ は可能であるか？これに優位性はあるだろうか？ （旧来の Linux アプリ資産を持つ開発者の立場）
