Abstract:
1. A digital processing apparatus for a mobile communication terminal, the digital processing apparatus comprising: a plurality of supplemental control units having first and second supplementary control units, each of the first and second supplementary control units configured to perform a predetermined supplementary function, wherein the supplementary function includes at least one of the functions including a camera function and a multimedia data playback function of the mobile communication terminal, the each of the first and second supplementary control units further configured to determine whether the each of the first and second supplementary control units are in a non-operating state for performing the predetermined supplementary function; a plurality of memory units including first and second supplementary memory units, each of the first and second supplementary memory units coupled to the first and second supplementary control units, respectively; and a main control unit coupled to the first and second supplementary control units, and configured to control the first and second supplementary control units, the main control unit coupled to the each of the first and second supplementary memory units through the first and second supplementary control units, wherein each of the plurality of supplementary control units has a permission structure for permitting one of the main control unit and the second supplementary control unit to directly access the second memory unit when an additional storage is needed by the one of the main control unit and the second supplementary control unit, when the additional storage is needed by the one of the main control unit and the second supplementary control unit and the first supplementary control unit does not occupy a bus that connects to the first supplementary memory unit due to the non-operating state of the first supplementary control unit, the first supplementary control unit uses a bypass logic to switch a route to directly couple the one of the main control unit and the second supplementary control unit with the first supplementary memory unit using the permission structure, and wherein the bypass logic changes the route based on an operating status of the plurality of supplemental control units, and is used to switch the route when the first supplementary control unit is not operating.
