An apparatus and method are disclosed for partitioning and dowloading executable memory images in low-powered computing devices comprised of multiple processors and a mobile station modem. The general computing subsystem (102) handles tasks generally related to a personal digital assistant (PDA) as well as activating the modem computer subsystem (104) and one or more shared memory modules (108-110). The modem computing subsystem (104) handles tasks associated with a mobile station modem. Power is conserved by not clocking the modem computer system (104) and the shared memory (108-110) during times when modem functions are not needed. The shared memory modules (108-110) are loaded with a binary memory image for use by the moedm computer subsystem (104) form a memory (222) under control of the general computing subsystem (102). When needed, the modem computing subsystem (104) is activated to monitor a paging channel, and disabled when it is no longer desired to monitor the paging channel. Additionally, a second shared memory (110) may be activated and used only when the modem computing system (104) needs to manage a traffic channel. |
