Electronic device for scheduling based on heterogeneous multi-processor and operating method thereof

An electronic device comprising:

• a memory;
• and
• a processor operatively connected to the memory and including a plurality of heterogeneous cores, wherein the processor is configured to:
• identify, when a task to be scheduled occurs, a scheduling group having the task among a plurality of predefined scheduling groups, and
• perform scheduling for the task, based on the identified scheduling group having the task and a priority of the task, by:
• identifying, based on the priority of the task and at least one reference value for classifying a plurality of subgroups, a subgroup having the task among the plurality of subgroups included in the scheduling group having the task,
• identifying one or more cores available in the subgroup having the task among the plurality of heterogeneous cores, and
• allocating the task to one of the one or more cores,
• wherein the at least one reference value is set based on at least one of a number of tasks included in each subgroup, a number of waiting tasks for core allocation in each subgroup, an execution state of an application related to a task, or a battery state of the electronic device.
