摘要:
Systems and methods of managing operating points provide for determining the number of active cores in a plurality of processor cores. A maximum operating point is selected for at least one of the active cores based on the number of active cores. In one embodiment, the number of active cores is determined by monitoring an ACPI processor power state signal of each of the plurality of cores.
摘要:
For one disclosed embodiment, a processor comprises a plurality of processor cores to operate at variable performance levels. One of the plurality of processor cores may operate at a performance level different than a performance level at which another one of the plurality of processor cores may operate. Logic of the processor is to monitor activity of one or more of the plurality of processor cores. Logic of the processor is to constrain power of one or more of the plurality of processor cores based at least in part on the monitored activity. Other embodiments are also disclosed.
摘要:
For one disclosed embodiment, a plurality of processor cores of a multicore processor may be operated at variable performance levels. One processor core may operate at a performance level different than a performance level at which another processor core may operate. Performance levels of multiple processor cores may be identified. Power consumption of the plurality of processor cores may be controlled based at least in part on the identified performance levels. Other embodiments are also disclosed.
摘要:
Briefly, a processor and a method of estimating an active energy consumption of two or more cores of a processor based on dispatching micro operations to one or more execution units of the processor.
