A scheduling method includes calculating required performance for a given task, calculating use performance and real performance of a candidate processor, calculating power corresponding to the real performance, calculating expected energy usage of the candidate processor based on the required performance, the use performance, the real performance, and the calculated power and calculating performance efficiency of the candidate processor by considering a ratio of the expected energy usage to the real performance.

Scheduling tasks based on calculated processor performance efficiencies

A computing system includes an ISA identifier to identify an ISA (Instruction Set Architecture) of a task; a core selector to select a core having a highest power-performance efficiency among a plurality of cores based on the identified ISA; and a task allocator to allocate the task to the selected core.

Computing system and method for operating computing system

A method of operating a system-on-chip (SOC) including a central processing unit (CPU) and a target hardware to which a dynamic voltage and frequency scaling (DVFS) is applied, includes determining an operating scheme of the target hardware, setting a DVFS application scheme for applying the DVFS to the target hardware, based on the operating scheme of the target hardware, and performing the DVFS on the target hardware, based on the DVFS application scheme.
