近年來手持式行動裝置漸漸的為大眾所接受，除使用者大量成長以外各式各樣的應用也不斷的發展並且推陳出新，因此以手持式行動裝置為平台的軟體開發成為各界致力發展的一環。另一方面，自從上個世紀以來由生產導向轉變為娛樂消費來主導社會，已經在許多地區以及國家實現或是正進入過渡期，在日本和韓國遊戲產業甚至已經超越了傳統製造業，而隨著玩家的型態改變，電腦遊戲平台從主流的個人電腦(PC)以及各式各樣的電玩主機逐漸的擴展到更接近玩家的諸如手機、PDA、筆記型電腦等，因應人們生活型態的改變以及各項裝置的多元化多媒體化，在行動裝置上電腦遊戲已經成為了必備的一環。目前關於電腦遊戲的研究多著重在電腦人工智慧(AI)的效能、電腦視覺、以及社會科學方面的討論。然而現階段各種的行動嵌入式系統、可攜式電腦等都受到有限的能源影響，在電池技術的開發進步緩慢下，不論是在硬體或軟體層面各項低功率技術逐漸的被發展以及應用，卻獨獨在電腦遊戲上目前仍沒有相關的研究。這篇論文因此針對這個問題，提出一套方法來對現有的遊戲作功率分析，並找出遊戲演算法的功率消耗特性，以供遊戲開發者於省電考量上有個依據。

Handheld PDAs are rapidly gaining in popularity and the capabilities of such devices are increasing at an accelerated pace. Computer game is one of the software applied in most mobile embedded devices that be re-quested to handle more and more functions in recent year. Most re-searches of computer games focus on AI performance, computer vision, even social sciences. On the other hand, a large and increasing number of embedded systems are subject to tight power constraints, but strangely no one pays attention to the games on mobile embedded device at present. Our work recognizes the need to provide embedded software designers with feedback about the effect of different algorithms of computer games on energy consumption early in the design cycle. The ability to efficiently analyze battery life under different design choices of games is an impor-tant aid in designing battery-efficient systems. In this paper, we present a comprehensive analysis of energy requirements in a wide range of the most used algorithms in different computer game types.
Based on our results, we conclude and discuss various opportunities for realizing energy-efficient implementations of game algorithms. We be-lieve that such investigations will be an important first step towards ad-dressing the challenges of energy efficient algorithms for bat-tery-constrained systems.
