2 Hardware Temperature Protection of TI Processors

Previous sections primarily introduced the hardware temperature management module in TI processors, which is responsible for managing temperature. The VTM module can read the values from on-chip temperature sensors. After obtaining the temperature, VTM performs thermal protection for the entire SOC hardware based on the measured temperature.
