ABSTRACT:
First (embedded) and second (non-embedded) processors are energized by an energy source in a hand-held device. The second processor performs functions requiring more power than those performed by the first processor. The second processor is normally asleep and is awakened by the first processor and is empowered, when awakened, to perform functions. Only the portions of the second processor required to perform these functions are activated. Protocols for functions to be performed by the second processor are provided initially to the second processor and are processed in the second processor. They are then transferred to the first processor for storage. When the second processor is activated to perform functions represented by a protocol, the protocol is transferred to the second processor and the functions are performed by the second processor.
