ELECTRONIC DEVICE HAVING FUNCTION FOR SELECTING OPERATION MODES OF DIFFERENT CONSUMPTION POWER AND METHOD FOR CONTROLLING POWER

摘要

PURPOSE: An electronic device having a function for selecting operation modes of different consumption power and a method for controlling the power are provided to effectively restraint power consumption caused by circuit blocks of the large consumption power. CONSTITUTION: The first circuit block(300) processes data. The second circuit block(107,109,110,111,112,128) performs a process associated with network routing. A controller(116) selects the operation mode from the first operation mode supplying the power to the first and the second circuit block, and the second operation mode supplying the power to the second circuit block and supplying no power to the first circuit block.
