CPC classification number: G06F1/3209 ,  G06F1/3231

Abstract: The information processing apparatus includes a computation processing circuit of which a state is capable of being switched at least between an active state in which power is consumed, and a no-power-usage state in which power is not consumed; an event detection module that detects a first event used to shift the state of the computation processing circuit from the no-power-usage state to the active state; a power isolation circuit that isolates power of the event detection module from power of the computation processing circuit in the no-power-usage state; and an isolation canceling circuit that cancels, in the active state, the isolation performed by the power isolation circuit.
