METHOD FOR SYNCHRONIZING UNBLOCKING OF CLOCK SIGNAL IN ELECTRONIC DEVICE Russian patent published in 2006 - IPC G06F1/12 G06F1/32 H04M1/73 

FIELD: electronic engineering.

SUBSTANCE: method for synchronization of unblocking of common clock generator for main and secondary processors in electronic device, having low power mode, includes first stage for completing communicating activity by main processor. Further, signal for unblocking clock signal from secondary processor is tracked. Timing of second processor is compared to known timing of main processor, if second processor failed to unblock clock generator at tracking stage. Timing is computed, necessary for synchronization of unblocking of clock generator by second processor with appropriate action of main processor. Second processor is enabled and disabled under control of main processor for synchronization of periodic timing of second processor with timing of main processor.

EFFECT: decreased consumption of energy by clock generator.
