碩士 === 國立臺灣大學 === 資訊工程學研究所 === 95 === 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.
