Abstract
A method and apparatus for improving power consumption characteristics of a system having an active mode and a low power mode. A signal source, such as a system clock, switches when the system is in active mode and does not switch when the system is in low power mode. An activity monitor is coupled to the signal source to detect if the signal source is switching. Based on the detection, the activity monitor drives switching control logic. The switching control logic disconnects nonessential auxiliary circuits from the power supply in response to a detection of a non-switching condition. When switching resumes, the switching control logic is driven by the activity monitor to restore power to the auxiliary circuit fast enough that power up does not delay system operation.
