ABSTRACT:
A power control apparatus for controlling power used by a digital electronic device having a plurality of processing devices for example, a CPU and a plurality of I/O controllers as well as a memory for storing power control instructions. The CPU is configured to output power control signals via one of the I/O controllers based on the signals or power control instructions. A microcomputer is provided to which the power control signals are input and which are configured to control power and clock frequency supplied to each one of the plurality of processing devices based on the power control signals. The microcomputer detects the input of the power control signal, sets power control bits for the plurality of processing devices into a data register based on the detection, and outputs via the I/O port the contents of the data register to control the power to each of the plurality of processing devices.
