Abstract
A system and method are provided for using a thermal management core to control temperature on a system-on-chip (SoC). The method provides an SoC with an internal thermal management core and an internal temperature sensor. For example, the sensor may be located on or near a processor core die. The thermal management core monitors temperatures recorded by the SoC temperature sensor, and sends commands for controlling SoC device functions. In response to these commands, the thermal management core monitors a change in the temperature at SoC temperature sensor. The temperature sensor may be monitored via a dedicated SoC internal interface connecting the processor and the thermal management core. Alternately, the thermal management core may poll for temperatures via a system management bus (SMBUS) SoC external interface connecting the processor and thermal management core. Further, a dedicated SoC external alert interface connecting the processor and thermal management core may be monitored.
