Method, apparatus, and system for energy efficiency and energy conservation including configurable maximum processor current

摘要

An apparatus, method and system is described herein for providing multiple maximum current configuration options including corresponding turbo frequencies for a processing device. Available options for a processor are determined by initialization code. And based on platform electrical capabilities, an optimal one of the multiple current configuration options is selected. Moreover, during runtime another current configuration is dynamically selected based on current configuration considerations to provide high flexibility and best possible performance per part and computing platform.

1. A processor comprising:
a plurality of processing elements; storage to hold a representation of a plurality of maximum current configurations for the processor, each of the maximum current configurations to be associated with a plurality of maximum turbo frequencies to be stored in the storage; and a turbo module adapted to dynamically select a maximum current configuration of the plurality of maximum current configurations based on a power event, to determine a number of the plurality of processing elements that are active and, based on the number of the plurality of processing elements that are active, to determine a maximum turbo frequency of the plurality of maximum turbo frequencies associated with the selected maximum current configuration.
