Abstract:
Embodiments contained in the disclosure provide a method and apparatus for device specific thermal mitigation. The thermal and power behavior of the device, is characterized. A thermal threshold is then determined for the device. The thermal data and thermal ramp factor for each device are determined and stored in a cross-reference matrix. A correlation factor is determined for temperature and frequency. These correlation factors determine a device mitigation temperature. The device mitigation temperature may be stored in a fuse table on the device, with a fuse blown on the device to permanently store the device mitigation temperature. The apparatus includes: an electronic device, a memory within the electronic device, and a set of fuses within the electronic device. The device also includes means for determining if a static or dynamic frequency is high, and means for mitigating a voltage and frequency used by the device, based on that determination.
