THERMAL MANAGEMENT IN A COMPUTING DEVICE BASED ON WORKLOAD DETECTION

摘要

Thermal management in a portable computing device differentiates between a temperature increase caused by a steady workload and a temperature increase caused by an instantaneous workload. If it is determined that a detected temperature increase is caused by a steady workload, then a configuration of thermal parameters is applied that optimizes thermal performance for a steady workload. If it is determined that a temperature increase is caused by an instantaneous workload increase, then a configuration of thermal parameters is applied that optimizes thermal performance for an instantaneous workload. The device includes at least one first temperature sensor on an integrated circuit die and at least one second temperature sensor not on the integrated circuit die but within a housing of the portable computing device. The workload is determined by computing a difference between a first temperature value responsive to the at least one first temperature sensor and a second temperature value responsive to the at least one second temperature sensor and comparing the difference with a threshold value.
