System and method for optimizing electrical power consumption by changing CPU frequency including steps of changing the system to a slow mode, changing a phase locked loop frequency register and changing the system to a normal mode

摘要

A system and a method for optimizing power in an electronic device are described. The system may be used to implement low power techniques to achieve maximum performance with low battery utilization. A processing load level monitor monitors load(s) on processors. Processor frequencies are updated through the driver until the load is close to 100%, which means that the core frequency is changed to the load processor around 100% at the minimum possible frequency.
