Title:
POWER-SAVING TRIGGER-TYPE CONTROL DEVICE FOR INSTANTLY VARYING FREQUENCY AND METHOD THEREOF
Document Type and Number:
Japanese Patent JP2011003174
Kind Code:
A
Abstract:

To provide a power-saving trigger-type control device for instantly adjusting frequency, and a method thereof.

The device includes a signal control unit having at least two signal input terminals, a counting control unit, and a clock generator. The two signal input terminals respectively receive trigger actions and then generate increment trigger signals and decrement trigger signals each counting to the same number as the corresponding trigger actions. The counting control unit counts the increment trigger signals or decrement trigger signals. The clock generator linearly increments or decrements output frequency according to the count of the increment trigger signals or decrement trigger signals. The device further has a power controller to regulate output voltage. The present invention can dynamically and instantly vary the frequency/voltage of the system via external control actions in any case to achieve power efficiency.
