技術名稱: Linux based 快速啟動技術/ 快速開機

技術簡介

採取休眠/喚醒方式讓系統進入無需耗電的關機狀態, 再運用軟硬體技術,讓系統在5秒內完成開機 (以 Android系統為例,需開機至桌面顯示的狀態)。 技術重點如下描述: ‧休眠改善技術:減少儲存空間需求,同時縮短資料搬移 時間,加快開機速度 ‧開機平行化技術:平行化開機程序,加快系統回復速 度. ‧開機流程優化技術:提升boot loader與 kernel/device初始化效率,節省開機時間

Abstract

With this fast booting technology, the system can accomplish booting procedure within 5 seconds and it can also power off completely without any power consumption. The major features include hibernation procedure improvement、booting procedure parallelization and optimization for device driver initialization.

技術規格

Linux Based快速開機技術,5 秒內開機至Android桌 面。 (以Flash或eMMC為儲存裝置,不需要額外特殊硬體)

Technical Specification

Linux based system. Android OS boot to the desktop within 5 seconds* (depends on hardware configuration). Using Flash/eMMC as the storage device, no specifically designed hardware is needed.

技術特色

行動智慧裝置為了維持使用者隨開隨用之快速啟動需求,通常在待機狀態會處於持續耗電狀態。本技術藉由專利之開機映像檔 縮減技術,與開機流程優化技術,可讓裝置完全關機不耗電,而開機時也能快速回復到可操作狀態,避免不必要之耗電達到節 能環保的效果。

應用範圍

多媒體連網電視(機上盒)、車用多媒體裝置(導航、影音設備或ADAS系統),或其它需要較長時間待機之嵌入式Linux(或 Android)平台。

接受技術者具備基礎建議(設備)

具備ARM Cortex A CPU的嵌入式硬體平台。

接受技術者具備基礎建議(專業)

具備基礎Embedded Linux kernel/ driver開發能力。
