摘要： Disclosed is an apparatus for dynamic thermal management, which includes a thermal management unit that determines whether there is a need to perform thermal management on a processor based on temperatures measured from a plurality of temperature sensors included in the processor and generates an indication signal, and a controller that performs the thermal management on the processor in response to the indication signal, by using a first method of adjusting a state of each of a plurality of cores included in the processor, a second method of adjusting a level of an operating voltage and a frequency of a clock signal, which are provided to the processor, and/or a third method for adjusting only the frequency of the clock signal to be provided to the processor, and where each of the plurality of cores is in a wake-up state or an idle state.

摘要： An operating method of a system-on-chip (SoC) which includes a processor including a first core and a dynamic voltage and frequency scaling (DVFS) module and a clock management unit (CMU) for supplying an operating clock to the first core, the operating method including: obtaining a required performance of the first core; finding available frequencies meeting the required performance; obtaining information for calculating energy consumption for each of the available frequencies; calculating the energy consumption for each of the available frequencies, based on the information; determining a frequency, which causes minimum energy consumption, from among the available frequencies as an optimal frequency; and
adjusting an operating frequency to be supplied to the first core to the optimal frequency.
