中文摘要：
该文针对支持电压频率岛的NoC能耗优化问题,提出了基于电压频率岛划分、分配以及任务映射的能耗优化方法。该方法通过基于处理器可靠性约束的电压频率岛划分,降低了处理器能耗;利用近凸区域选择的电压频率岛分配策略,减少了不同电压岛间复杂路由器的个数;借助量子粒子群算法优化了NoC映射,降低了系统的通信能耗。实验结果表明,该文算法在满足NoC处理器可靠性要求的前提下,可显著降低NoC系统能耗。
英文摘要：
A method for energy optimization based on the partitioning,assignment,and task mapping of voltage-frequency islands is proposed,considering the issue of energy optimization of Network-on-Chip（NoC） that supports voltage-frequency islands.The energy consumption of the processor is reduced by the partitioning of voltage-frequency islands under processor reliability constraints;the number of complex routers between different voltage-frequency islands is decreased by the voltage-frequency islands assignment strategy of near convex region selection;and the energy consumption of system communications is reduced through NoC mapping optimizations by quantum-behaved particle swarm algorithm.Experimental results show that the presented algorithm can significantly reduce the NoC system energy consumption with the requirements of NoC processor reliability satisfied.
