摘要
动态电压调节是一种有效的节能技术.本文提出了多核处理器平台上的一种近似最优的动态电压调节算法.算法将电压调节问题转化为松弛时间分配问题,由任务集结构找到存在的松弛时间,针对不同类型的松弛时间,使用了并行补偿等分配方法.实验结果表明本文的算法能够有效的降低能量消耗且具有较低的时间复杂度.
The method of dynamic voltage scaling （DVS） is an efficient technology for saving energy. This paper put forwards a near-optimal strategy on multi-core processor using DVS .It changes the problem of voltage scaling to the problem of slack time allocation.It detects the slack time based on task structure firstly. Aiming at different kinds of slack times,it then uses relevant allocating method such as parallel compensate algorithm. Result of the experiment indicates that the strategy of this paper can decrease the energy consumption efficiently and has low complexity.
