Abstract
A portable computing device includes a modem and an application processor communicatively coupled by a data bus. The modem communicates a target data throughput in accordance with an identified data call. In response, the application processor determines whether an adjustment of an interrupt latency threshold is warranted to support the target data throughput identified by the modem. Otherwise, the application processor executes no such adjustment. In addition, the modem requests a desired performance of an application processor resource. In response, the application processor adjusts a control input of the application processor controlled resource. A change in a present data transfer session triggers the modem to communicate a revised target data throughput and/or a revised request for a desired performance of an application processor resource.
