Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0179164 filed with the Korean Intellectual Property Office on December 26, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to electronic devices and methods of operation thereof. Background technique [0004] In a system-on-chip (SoC) in which a plurality of devices of an electronic device are integrated on one chip, power management may be easily performed. In some cases, the dynamic power of a device integrated on an SoC may be reduced if and / or when clock gating for disabling the clock of the device integrated on the SoC is performed. In some cases, if and / or when clock gating is performed for a particular device, the central processing unit (CPU) may access the device's drivers to check the work queue, and if the work queue is empty, the CPU may determine The...
