Temperature Management Circuit, System on Chip Including the Same and Method of Managing Temperature

摘要

In managing temperature in a system on chip (SOC), a main temperature signal is generated using a main sensor, where the main temperature signal is a signal having a value corresponding to a main temperature of the SOC. Subsidiary temperature signals are generated using subsidiary sensors, where the subsidiary temperature signals are pulse signals having frequencies corresponding to subsidiary temperatures of subsidiary blocks in the SOC, respectively. An operation of the SOC is controlled based upon the main temperature signal and the subsidiary temperature signals.
