摘要(中)在這論文裡,我們藉由分析可調型電源管理的非時變穩態機率模型,找尋資訊手機電能使用效率與資訊處理延遲之關係。當行動資訊多媒體系統利用可調型電源管理時,系統可以在低電源功率消耗狀態下等待資訊的累積,當在資訊佇列裡的資訊累積到一定數量後,系統會轉態為忙碌狀態而開始處理資訊。如果我們能忍受多媒體系統利用可調型電源管理造成約三至五倍的延遲,那麼我們會有潛力可以節省約70%電源的消耗。再說一般使用者比較不願意看斷斷續續的畫面,而可調型電源管理方式也修正了這個缺點。因此可調型電源管理應用在行動多媒體系統是可行的。
摘要(英)Based on the analysis of the stationary non-time-varying state probability model, this paper shows the relationship between power efficiency and latency of mobile information processing under a scalable power management method. According to the scalable information processing model, the mobile terminal can work at the waiting state with low power consumption and in the meantime accumulate information in the terminal information queue. When the amount of the accumulated information reaches a preset level, then the machine can switch to busy state and process the accumulated information. In an ideal situation, we have a potential to save around 70% power consumption, if we can tolerate around five times the latency of a real time palmtop multimedia terminal. Furthermore, a mobile user would rather like to watch a whole piece of information instead of seeing the fragments of a picture sporadically. Therefore, the scalable power management model for a palmtop multimedia terminal can be acceptable.
