Predictive runtime thermal management systems and methods

A system for performing predictive run-time thermal mitigation in a processor, the system comprising:

• at least a first temperature sensor and a first power sensor or meter configured to measure a current junction temperature, TJUNC, value and a current power, PTOTAL, value consumed by the processor, respectively;
• logic configured to predict what a temperature, TEMPPRED, value of the processor will be in n sample periods from a current sample period of the processor based at least in part on the current TJUNC and current PTOTAL values, where n is a positive integer;
• logic configured to determine if the TEMPPRED value exceeds a preselected temperature threshold, THTEMP, value;
• and
• logic configured to cause one or more thermal mitigation actions to be taken to ensure that a future TJUNC value measured n sample periods from the current sample period k of the processor will not exceed the THTEMP value if the TEMPPRED value exceeds the preselected THTEMP value.

A computer program embodied on a nontransitory computer-readable medium and comprising computer instructions for execution by a processor for causing the processor to perform predictive run-time thermal mitigation in a processor, the computer program comprising:

• a first set of computer instructions for receiving a current junction temperature, TJUNC, value and a current power, PTOTAL, value consumed by the processor measured by at least a first temperature sensor and a first power sensor or meter, respectively;
• a second set of computer instructions for predicting what a temperature, TEMPPRED, value of the processor will be in n sample periods from a current sample period, k, of the processor based at least in part on the current TJUNC and current PTOTAL values, where k and n are positive integers;
• a third set of computer instructions for determining if the TEMPPRED value exceeds a preselected temperature threshold, THTEMP, value;
• and
• a fourth set of computer instructions for causing one or more thermal mitigation actions to be taken if the TEMPPRED value exceeds the preselected THTEMP value.
