1. A method for reducing power consumption in a portable computing device, the method comprising: detecting, in a modem, a present data call type; transmitting, from the modem, a target data rate responsive to the data call type; receiving, in an application processor, the target data rate; using the application processor to dynamically adjust an interrupt latency threshold to a level capable of supporting the target data rate; transmitting, from the modem, a desired performance of a resource used by the application processor; and dynamically adjusting the resource to meet the desired performance.
