Apparatus and method for controlling power of electronic device having multi-core

摘要

A method of controlling on/off of a core based on a used amount of an operating core and the number of tasks in an electronic device having a multi-core, and an apparatus thereof, includes confirming a load of an operating core and the number of executable tasks at a predetermined period, determining whether the load of the operating core and the number of executable tasks meet a defined on/off condition of the multi-core, and controlling on/off of the multi-core when the load of the operating core and the number of executable tasks meet the defined on/off condition of the multi-core.

1. A method of controlling power of an electronic device having a multi-core, the method comprising:
confirming a load of an operating core and the number of executable tasks at a predetermined period; changing an operation frequency of the operating core according to the load of the operating core; and controlling on/off of the multi-core if the load of the operating core and the number of executable tasks satisfy a defined on/off condition of the multi-core that is set according to current consumption characteristics of the multi-core, wherein controlling on/off of the multi-core comprises identifying whether a current operation frequency of the operating core is greater than or equal to a preset reference frequency if the defined on/off condition is satisfied, and wherein the predetermined period includes a core ON period for confirming an ON of an additional core and a core OFF period for confirming an OFF of the operating core.
