Method and system for optimizing performance of a PCD while mitigating thermal generation

A temperature of a component within the portable computing device (PCD) may be monitored along with a parameter associated with the temperature. The parameter associated with temperature may be an operating frequency, transmission power, or a data flow rate. It is determined if the temperature has exceeded a threshold value. If the temperature has exceeded the threshold value, then the temperature is compared with a temperature set point and a first error value is then calculated based on the comparison. Next, a first optimum value of the parameter is determined based on the first error value. If the temperature is below or equal to the threshold value, then a present value of the parameter is compared with a desired threshold for the parameter and a second error value is calculated based on the comparison. A second optimum value of the parameter may be determined based on the second error value.
