| Summary: | 碩士 === 國立中興大學 === 資訊科學研究所 === 94 === During the past few years, with the dramatic improvement of information technology , modern disk can transmit data in high rotational speed and provide large capacity. However, the disk energy consuming still not improved that limits mobile computer’s battery lifetime. In this paper, we build a disk power-aware scheduling scheme based on energy efficient pre-fetching and caching to extend disk idle time in the low power mode. We provide three scheduling algorithms listing as follows:
1. Disk in spinning mode task scheduling algorithm.
2. Disk in spin down mode task scheduling algorithm.
3. Task remains pre-fetch data smaller than threshold task scheduling algorithm.
By applying these three power management schemes can extend mobile computer’s battery lifetime with dramatically improvement.
