<p>PROBLEM TO BE SOLVED: To provide a low-power audio processor capable of reducing power consumption. SOLUTION: The audio processor is separated into a BSP unit 100, a DS unit 110 and a post processing unit 120 by functions for audio signal processing. A power control unit 140 analyzes the states of the respective units to decide the state of power, and an internal clock signal generation part generates a clock signal so as to operate only one of the three processing unit in accordance with the decided state of the power. Thus, only the pertinent unit directly participating in processing is driven in processing.</p> |
