DEVICE FOR SAVING POWER SUPPLY OF PORTABLE TERMINAL AND METHOD THEREFOR, ESPECIALLY REGARDING TO MINIMIZING POWER CONSUMPTION BY PERIODICALLY DETECTING PAGING SIGNALS AND DETECTING INTERRUPT SIGNALS BY OPERATING INTERRUPT ROUTINE

摘要

PURPOSE: A device for saving power supply of a portable terminal and a method therefor are provided to minimize power consumption by periodically detecting paging signals and detect interrupt signals by operating an interrupt routine, thereby increasing hours for using a battery of a portable terminal. CONSTITUTION: A power supply unit(110) outputs operating power supply to each functional unit of a mobile terminal. A control unit(200) monitors and controls each functional unit. A clock unit(300) selectively outputs an inner clock signal by a control signal applied from the control unit. A digital baseband unit(400) processes a digital baseband signal by the inner clock signal and wirelessly connects to a base station. A flash memory(500) outputs a stored program. An SRAM(Static Random Access Memory)(600) stores variable data and outputs the stored data. A melody camera unit(700) outputs a melody signal and processes an image signal. An audio unit(900) processes a voice signal.
