Abstract: Provided is a graphics processing unit and an operation method thereof. The graphics processing unit includes a plurality of cores in which a delay time between an input and an output decreases according to an increase of a temperature, a temperature monitoring and sorting circuit configured to monitor a temperature of each of the plurality of cores, and a controller configured to control a clock frequency and a power supply of the plurality of cores based on a drivable clock frequency of a core having the lowest temperature among temperatures of each of the plurality of monitored cores.

Abstract: Provided is a network-on-chip (NoC). The NoC includes a plurality of routers configured to receive power through each corresponding power gating switch, and a controller configured to control a power gating switch of each of the plurality of routers based on temperature information provided from each of the plurality of routers and control a driving clock of the plurality of routers. The controller controls the power gating switch to turn off at least one first router by referring to the temperature information and over-scale a clock frequency of at least one turned-on second router.
