Abstract
An apparatus and method are disclosed for partitioning and downloading executable memory images in low-powered computing devices comprised of multiple processors and a mobile station modem. The general computing subsystemhandles tasks generally related to a personal digital assistant (PDA) as well as activating the modem computer subsystemand one or more shared memory modules-. The modem computing subsystemhandles tasks associated with a mobile station modem. Power is conserved by not clocking the modem computer systemand the shared memory-during times when modem functions are not needed. The shared memory modules-are loaded with a binary memory image for use by the modem computer subsystemfrom a memoryunder control of the general computing subsystem. When needed, the modem computing subsystemis activated to monitor a paging channel, and disabled when it is no longer desired to monitor the paging channel. Additionally, a second shared memorymay be activated and used only when the modem computing systemneeds to manage a traffic channel.
