Dynamic processor core switching is described. In embodiments, a multi-core processor system can include a first processor core that executes computer instructions at a first processing rate, and can include at least a second processor core that executes the computer instructions at a second processing rate, where the second processing rate is different than the first processing rate. A core profiler can generate system profile data that is evaluated to determine when a core-switch manager initiates switching execution of the computer instructions from the first processor core to the second processor core while the computer instructions are being executed.

Dynamic processor core switching

Some of the embodiments of the present disclosure provide a method comprising generating a plurality of power profiles for a corresponding plurality of processing cores, wherein each power profile of the plurality of power profiles includes power consumptions of a corresponding processing core under various operating conditions; generating a plurality of candidate configurations, wherein each candidate configuration comprises corresponding candidate operating conditions for the plurality of processing cores; and based at least in part on the plurality of power profiles, selecting a first candidate configuration of the plurality of candidate configurations for managing the plurality of processing cores. Other embodiments are also described and claimed.
