Abstract:
In an embodiment, a processor includes: a plurality of first cores to independently execute instructions, each of the plurality of first cores including a plurality of counters to store performance information; at least one second core to perform memory operations; and a power controller to receive performance information from at least some of the plurality of counters, determine a workload type executed on the processor based at least in part on the performance information, and based on the workload type dynamically migrate one or more threads from one or more of the plurality of first cores to the at least one second core for execution during a next operation interval. Other embodiments are described and claimed.
