Patent ID: 7587619

Claim:
A method for saving power in a multi-processor wireless communication system having a paging channel monitor mode, the method comprising: booting a general computing subsystem; gating clocking of a modem computing subsystem and at least one shared memory module upon the booting of the general computer subsystem to disable the modem computing subsystem until the modem computing subsystem is needed, wherein the at least one shared memory module comprises a first modem boot code partitioned separately from a second modem boot code, wherein the first modem boot code enables a paging channel monitor mode of the modem computer subsystem, wherein the second modem boot code enables a traffic channel monitor mode of the modem computer subsystem; enabling the modem computing subsystem when monitoring of a paging channel is desired and entering the paging channel monitor mode, wherein the enabling includes loading the first modem boot code for the paging channel monitor mode while not loading the second modem boot code for the traffic channel monitor mode; and disabling the modem computing subsystem to conserve power and exiting the paging channel monitor mode when monitoring of the paging channel is not desired.
