摘要：Optimization of a parameter can be achieved by a servo loop having a temperature sensor, a temperature change detector, and a parameter adjuster. The temperature sensor monitors the temperature of an electronic device while the parameter is varied. The temperature change detector detects whether the electronic device temperature is increasing or decreasing. The parameter has a value associated with minimum power consumption when the monitored temperature reaches a minimum. The parameter is adjusted dynamically to a new preferred value as operating conditions of the electronic device change.
