| Zusammenfassung: | To provide an information processing apparatus capable of delaying the drop of supply voltage to a nonvolatile memory when a power failure occurs.SOLUTION: According to an embodiment, an information processing apparatus includes a processor, a nonvolatile memory, and a power supply voltage monitoring unit. The power supply voltage monitoring unit monitors power supply voltage which is input for the voltage for operating each module including the processor and the nonvolatile memory. The power supply voltage monitoring unit transmits an interrupt signal for stopping the processor to the processor when a voltage value of the power supply voltage falls below a threshold value.SELECTED DRAWING: Figure 1
【課題】電源断発生時における不揮発性メモリへの供給電圧の降下を遅延させることができる情報処理装置を提供する。【解決手段】実施形態によれば、情報処理装置は、プロセッサと、不揮発性メモリと、電源電圧監視部とを具備する。電源電圧監視部は、前記プロセッサおよび前記不揮発性メモリを含む各モジュールの動作電圧用に入力される電源電圧を監視する。前記電源電圧監視部は、前記電源電圧の電圧値が閾値を下回った場合、前記プロセッサを停止させるための割り込み信号を前記プロセッサへ送信する。【選択図】図１ |
