ABSTRACT:
A mobile electronic communication device power management method and apparatus are disclosed for use in multiple processor hardware schemes having asymmetrical power demands between processors. Upon reaching an long duration idle state, a high-level processor with high power consumption requirements handling low-level system tasks updates a data set shared between processor subsystems containing information necessary to perform such low-level tasks. A proxy software module is initiated on a base-band processor with lower power consumption requirements. The proxy module accesses the shared data set and begins to control low-level system tasks, allowing the high-level processor to enter a dormant low power state. Upon the occurrence of a wake-up event, the high-level processor enters an active state. The shared data set is updated by the proxy software module and the proxy module is terminated. The high-level processor accesses the shared data set and resumes control of low-level system tasks.
