Abstract: An operating method of a system-on-chip (SoC) which includes a processor including a first core and a dynamic voltage and frequency scaling (DVFS) module and a clock management unit (CMU) for supplying an operating clock to the first core, the operating method including: obtaining a required performance of the first core; finding available frequencies meeting the required performance; obtaining information for calculating energy consumption for each of the available frequencies; calculating the energy consumption for each of the available frequencies, based on the information; determining a frequency, which causes minimum energy consumption, from among the available frequencies as an optimal frequency; and



adjusting an operating frequency to be supplied to the first core to the optimal frequency.

Abstract: An apparatus and a method for scheduling a task in an electronic device including a heterogeneous multi-processor are provided. The electronic device includes a memory and a processor operatively connected to the memory and including a plurality of heterogeneous cores. The processor may be configured to identify, when a task to be scheduled occurs, a scheduling group having the task among a plurality of predefined scheduling groups, and to perform scheduling for the task, based on the identified scheduling group having the task and a priority of the task.
