Claim 16:
17. A mobile device comprising:
a processor including a plurality of cores and a plurality of temperature sensors;
a thermal management unit configured to determine whether there is a need to perform thermal management on the processor based on temperatures measured from the plurality of temperature sensors, and to generate an indication signal based on the indication;
a power management unit configured to provide powers to the plurality of cores, respectively;
a power management integrated circuit (PMIC) configured to provide an operating voltage to the processor;
a clock management unit configured to provide a clock signal to the processor; and
a controller configured to perform the thermal management on the processor in response to the indication signal, wherein the controller is configured to execute a first method for adjusting a state of each of the plurality of cores included in the processor, a second method for adjusting a level of an operating voltage and a frequency of a clock signal, or a third method for adjusting only the frequency of the clock signal, wherein the controller performs the thermal management using at least one of the first, second, or third methods, and
wherein each of the plurality of cores is in a wake-up state or an idle state, and
wherein each of the plurality of cores is one of:
a first core consuming a first power and having a first processing speed,
a second core consuming a second power less than the first power and a second processing speed slower than the first processing speed, or
a third core consuming a third power less than the second power and having a third processing speed slower than the second processing speed.
