Abstract:
Apparatuses, methods and storage medium associated with current control for a multicore processor are disclosed herein. In embodiments, a multicore processor may include a plurality of analog current comparators, each analog current comparator to measure current utilization by a corresponding one of the cores of the multicore processor. The multicore processor may include one or more processors, devices, and/or circuitry to cause the cores to individually throttle based on measurements from the corresponding analog current comparators. In some embodiments, a memory device of the multicore processor may store instructions executable to operate a plurality power management agents to determine whether to send throttle requests based on a plurality of histories of the current measurements of the cores, respectively.
