INFORMATION PROCESSING APPARATUS AND POWER SUPPLY CONTROL METHOD |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an information processing apparatus for saving power in both a control section and a converter and to provide a power supply control method. <P>SOLUTION: When a voltage detected by a DSP 200 reaches a fixed threshold value or less, the voltages output from D/D converter sections 207 are lowered by a specific rate while a PWM is controlled so as to lower the voltage supplied from the power supply 201 for the DSP to the DSP 200 by a specific rate. <P>COPYRIGHT: (C)2009,JPO&INPIT |
