Abstract
A mobile device is provided that includes a first processor coupled among at least one additional processor and a communication device for use in maintaining electronic files of the device. The mobile device can, for example, be a cellular telephone. The mobile device further includes an upgrade engine coupled to the first processor. The upgrade engine receives maintenance files from remote servers via the communication device, where the maintenance files include difference files. The upgrade engine uses information of the difference files to update software of the first processor. In addition to the upgrade engine, the mobile device includes an emulator that is coupled to the upgrade engine. The emulator transfers pre-specified ones of the difference files to the additional processor(s) where a rewrite engine uses the difference files to upgrade software of the additional processor(s).
