  • Patent number: 10203740
    Abstract: According to an embodiment, an information processing device includes a memory device, one or more peripheral devices, a processor, and a state controller. The processor is able to change between a first state, in which a command is executed, and a second state, in which an interrupt is awaited. When the processor enters the second state and if an operation for data transfer is being performed between at least one of the peripheral devices and the memory device, the state controller switches the information processing device to a third state in which power consumption is lower as compared to the first state. If the operation for data transfer is not being performed between any of the peripheral devices and the memory device, the state controller switches the information processing device to a fourth state in which power consumption is lower as compared to the third state.
