Method of dynamically adjusting the operating frequency and available power of a processor core of a handheld multimedia device using historical load characteristics

摘要

A technique is provided for use in a handheld multimedia device that uses the historical load profile statistics of a particular multimedia stream to dynamically scale the computational power of a computing engine, depending upon the complexity of the multimedia content and thereby reduce the power consumption for computationally less intensive content and consequently reduce the power consumption by a significant amount over a duration of time.
