摘要： Methods and systems for leveraging temperature sensors in a portable computing device (“PCD”) are disclosed. The sensors may be placed within the PCD near known thermal energy producing components such as a central processing unit (“CPU”) core, graphical processing unit (“GPU”) core, power management integrated circuit (“PMIC”), power amplifier, etc. The signals generated by the sensors may be monitored and used to trigger drivers running on the processing units. The drivers are operable to cause the reallocation of processing loads associated with a given component's generation of thermal energy, as measured by the sensors. In some embodiments, the processing load reallocation is mapped according to parameters associated with pre-identified thermal load scenarios. In other embodiments, the reallocation occurs in real time, or near real time, according to thermal management solutions generated by a thermal management algorithm that may consider CPU and/or GPU performance specifications along with monitored sensor data.
