摘要: | 嵌入式系統的設計開發人員,目前亟需一套精確可靠的能耗量測工具。MP3隨身聽是目前最普遍的掌上型多媒體播放器,其中續航力的問題,已成為一項重要的設計考量。在這篇論文中,我們改進一個在多工環境下,整合系統執行資訊的實體量測能耗分析工具,並透過大量的實驗,驗證這套工具,建立一套MP3能耗量測標準方法。實驗中,考慮到經過各種最佳化的MP3播放器,對不同長度、位元率或曲風的MP3歌曲,利用正規的統計方法,驗證量測結果的誤差。相信這套能耗量測分析工具的實驗方法,同樣能適用於其它應用上。 An accurate and reliable energy consumption measurement tool is very important for the designers of modern embedded systems. MP3 Walkman is almost the most popular hand-held multimedia player, and the endurance of a MP3 player has become an critical issue. In this thesis, we revise a physical measurement-based tool which integrates energy consumption with system execution information in multi-tasking systems. We validate this tool and establish a standard approach of MP3 energy measuring by a large number of experiments. Different optimizations of a MP3 player or variable lengths, bit rates, and music styles of a MP3 music are considered in the experiments, and we make use of a statistical approach to verify the measurement results. We believe the experiment approach using energy consumption measurement and analysis tool can be adopted to other applications as well. |
