摘要:
In an embodiment, a processor includes a plurality of cores each to independently execute instructions, a plurality of graphics engines each to independently perform graphics operations; and, a power control unit coupled to the plurality of cores to control power consumption of the processor, where the power control unit includes a power excursion control logic to limit a power consumption level of the processor from being above a defined power limit for more than a duty cycle portion of an operating period. Other embodiments are described and claimed.
摘要:
An apparatus, method and system is described herein for dynamic power control of a power domain. A power limit over a time window is provided. And over a control loop period a power interface determines energy consumption of the power domain, intelligently budgets power among devices within the power domain based on the energy consumption, converts those budgets to performance maximums for the power domain, and limits performance of devices in the power domain to the performance maximums utilizing a running average power limit.
