Abstract
A subprocessor is used to interface between subsystems and to reduce the amount of dedicated hardware used to implement the subsystems in a hand-held computer. The subprocessor includes basic processing system resources such as random-access memory (RAM), read-only memory (ROM), a processor, input/output (I/O) facilities, etc. Selected functions in subsystems are achieved by firmware instructions executed by the subprocessor as opposed to a main processor that is also used in the computer. This approach can provide efficiencies such as low power consumption, less required space, less routing overhead, easier transfer of inter-subsystem information, and other advantages.
