Abstract
A method for correcting audible noise from a voltage regulator due to a change of a VID indicated by a series of VID commands. A VID difference between a current value and a target value of the VID is compared with a VID threshold when a VID command for changing the VID from the current value to the target value is received. The VID is held at the current value if the VID difference is larger than the VID threshold. And the VID command is executed if a holding duration for holding the VID at the current value expires and no new VID command for changing the VID is received before the expiration of the holding duration.
