    摘要： The efficiency rating (ER) of each domain, in a processor, may be compared and then the power budget may be allocated, effectively, among the domains based on the ERs of the domains. The ER may indicate relative advantage among domains in terms of performance return for a given power budget, i.e., a higher effectiveness may be expected in power utilization if the ER is higher for a domain. The ER of a domain may be defined as (scalability factor/cost factor*alpha). The scalability factor may be defined as a performance increase (in %) brought about by an increase in the clock frequency (in %) provided to the domain. The cost factor may be defined as a power budget value required in bringing about an increase in the clock frequency provided to the domain and alpha is an adjustment factor.

    摘要翻译： 可以比较处理器中每个域的效率等级（ER），然后基于域的ER来在域中有效地分配功率预算。 对于给定的功率预算，ER可以指示域之间的性能回报方面的相对优势，即如果ER对于域更高，则在功率利用中可以预期更高的有效性。 域的ER可以定义为（可扩展性因子/成本因子*α）。 可扩展性因素可以被定义为由提供给域的时钟频率（以％计）的增加而导致的性能增加（以％计）。 成本因素可以被定义为使得提供给域的时钟频率增加所需的功率预算值，而α是调整因子。
