Abstract: Various embodiments of methods and systems for dynamically adjusting operating frequency settings of one or more processing components in a portable computing device (“PCD”) are disclosed. One such method involves receiving a request to adjust an operating frequency setting of a processing component to a required frequency (“F_req”) to process a workload. Factor readings associated with the operating capacity of the processing component may be taken. Based on the readings, performance curves associated with the processing component may be queried. The performance curves are used to determine the optimal operating frequency (“F_opt”) for the processing component. The F_opt is compared to the F_req and, if the F_req is less than F_opt, the operating frequency setting of the processing component is set to F_opt. Advantageously, as compared to F_req, at F_opt workload processing may be more efficient and a low power mode may be entered sooner.

Abstract: Systems and methods for real-time control of a bus operating point in a portable computing device (“PCD”) are presented. An indication of an event occurring in a bus interface is used as an indicator of a mismatch between a resource request and a data throughput level that can be supported by the bus. A suitable mechanism for identifying the mismatch provides a cost effective and non-invasive solution that is generally applicable for all usage situations.
