    • In some embodiments, an apparatus for an energy efficient clustered micro-architecture are disclosed. In one embodiment, the micro-architecture computes an energy delay2 product for each active instruction scheduler and one or more associated function blocks of a current architecture configuration over a predetermined period. Once the energy delay2 product is computed, the computed product is compared against an energy delay2 product calculated for a prior architecture configuration to determine an effectiveness (energy efficiency) of the current architecture configuration. Based on the effectiveness of the current architecture configuration, a number of active instruction schedulers and one or more associated functional blocks within the current architecture configuration is adjusted. In one embodiment, the number of active instruction schedulers and one or more associated functional blocks may be increased or decreased to improve power efficiency of the cluster micro-architecture. Other embodiments are described and claimed.
    • 在一些实施例中,公开了一种用于能量效率的集群微架构的装置。 在一个实施例中,微架构在预定时段内为每个活动指令调度器和当前体系结构配置的一个或多个相关功能块计算能量延迟2乘积。 一旦计算了energy delay2产品,将计算的产品与针对先前架构配置计算的能量延迟2乘积进行比较,以确定当前架构配置的有效性(能效)。 基于当前架构配置的有效性,调整当前架构配置中的多个主动指令调度器和一个或多个相关联的功能块。 在一个实施例中,可以增加或减少活动指令调度器和一个或多个相关联的功能块的数量,以提高集群微架构的功率效率。 描述和要求保护其他实施例。
