Data processing device for reducing power consumption while operating a virtualized environment, and a non-transitory computer-readable recording medium and integrated circuit for performing the same

摘要

A data processing device including an inter-VM notification management unit 1242, a resuming judgment unit 1244 and a scheduled interruption time acquisition unit 1245, such that, when it is necessary to notify a virtual machine in a power-saving state, the resuming judgment unit 1244 judges whether to cause the virtual machine to return from the power saving state, based on a time until an interruption acquired by the scheduled interruption time acquisition unit 1245. This structure prevents unnecessary transitions between states, and realizes the power saving for the apparatus.
