Kuan-Wen Lin, Ya-Shu Chen · 2015
Partial reconfigurable three-dimensional field programmable gate arrays are promising innovations for meet 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 an online thermal-aware task allocation algorithm for minimizing the system temperature under area constraints. 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 of the proposed methodology was evaluated using a series of workloads, and impressive results were obtained.
