Abstract: Methods and apparatuses control electrical current supplied to a plurality of processing units in a multi-processor system. A plurality of current usage information corresponding to the processing units are received by a controller to determine a threshold current for each of the processing units. The controller determines a frequency reduction action and an instructions-per-cycle (IPC) reduction action for the each of the processing units based on the threshold current and regulates operations of the processing units based on the determined frequency and IPC reduction actions.

Abstract: Methods and systems for facilitating improved power consumption control of a plurality of processing cores are disclosed. The methods improve the power consumption control by performing power throttling based on a determined excess power consumption. The methods include the steps of: monitoring using at least one event count component in the respective processing core a plurality of distributed events; calculating an accumulated weighted sum of the distributed events from the event count component; determining an excess power consumption by comparing the accumulated weighted sum with a threshold power value; and adjusting power consumption of the respective processing core based on the determined excess power consumption.
