碩士 === 國立臺灣科技大學 === 電機工程系 === 103 === Partial reconfigurable three-dimensional field programmable gate arrays are promising innovations for meeting the demand of implementing embedded systems demonstrating high area efficiency and excellent performance. However, thermal management has become a critical concern in three-dimensional integrated systems; this is because high system temperatures degrade system performance. This study proposes online thermal-aware task allocation algorithms for minimizing the system temperature under area constraints for both column-based and CLB-based three-dimensional field programmable gate array. In addition, an online thermal-aware swap algorithm is proposed for cooling the system through task reconfiguration for improving the system utilization. The thermal efficiency and run-time overhead of the proposed methodology was evaluated using a series of workloads, and impressive results were obtained.
