Temporal temperature sensor position offset error correction

An apparatus for correcting thermal sensor measurements on a die, comprising:

• means for receiving a temperature measurement of a region from a sensor;
• means for measuring activity of the region, the measured activity including current flowing in a device including the die, or performance of the device including the die, which is based at least in part on a determination of a number of cache misses or a number of pipeline stalls;
• means for converting the measured activity into power of the region;
• means for deriving a temperature offset by referencing stored thermal model parameters to interpret the power or the activity of the region;
• and
• means for adjusting the temperature measurement based at least in part on the temperature offset.

An apparatus for correcting thermal sensor measurements on a die, comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor being configured:
• to receive a temperature measurement of a region from a sensor;
• to measure activity of the region, the measured activity including current flowing in a device including the die, or performance of the device including the die, which is based at least in part on a determination of a number of cache misses or a number of pipeline stalls;
• to convert the measured activity into power of the region;
• to derive a temperature offset by referencing stored thermal model parameters to interpret the power or the activity of the region;
• and
• to adjust the temperature measurement based at least in part on the temperature offset.

A non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising:

• program code to receive a temperature measurement of a region from a sensor;
• program code to measure activity of the region, the measured activity including current flowing in a device including the die, or performance of the device including the die, which is based at least in part on a determination of a number of cache misses or a number of pipeline stalls;
• program code to convert the measured activity into power of the region;
• program code to derive a temperature offset by referencing stored thermal model parameters to interpret the power or the activity of the region;
• and
• program code to adjust the temperature measurement based at least in part on the temperature offset.
