ABSTRACT:
Systems and methods for dynamic power management of electronic devices are disclosed. In one form, a system employing dynamic power management for electronic devices includes a central processing unit operable to process information via a communication bus. The system includes a clock generator and a voltage generator coupled to the processing unit and operably associated with the communication bus having multiple operating voltage levels. The clock generator and communication bus are operated at variable clock rates and voltage levels to ensure bandwidth requirements are satisfied for communicating and processing information. In this manner, power consumption of the system may be dynamically managed while providing sufficient bandwidth for the system.
