Abstract
A system-on-chip includes a clock controller configured to decrease an operating frequency of at least one function block based on a change in an operating state of the at least one function block from an active state to an idle state. In a method of operating a system-on-chip including at least one function block, an operating frequency of the at least one function block is decreased based on a change in an operating state of the at least one function block from an active state to an idle state. The decreased operating frequency is greater than zero.
