    摘要： According to one embodiment, a computer system comprises a first memory that stores a first program, a second memory that stores a second program or data, a processor, a first and a second power control circuits. The first power control circuit causes the first memory to operate at a first power consumption when detecting change of an input signal to the processor, and causes the first memory to operate at a second power consumption smaller than the first power consumption and transmits a temporary halt instruction to the processor when the execution of the first program or the second program by the processor is completed. The second power control circuit causes the second memory to operate at a third power consumption before the processor executes the second program, reads or writes the data. The second memory accepts read and write operations while operating at the third power consumption.

    摘要： According to an embodiment, a control device includes a receiving unit, a judging unit, an estimating unit, a deciding unit, a directing unit, and a sending unit. The receiving unit is configured to receive an interrupt request requesting a processing device that includes elements capable of being individually subjected to voltage control to execute an interrupt process. The judging unit is configured to judge a state of the elements. The estimating unit is configured to estimate a start-up time for the element to change into an operating mode after power is supplied. The deciding unit is configured to decide a starting point in time at which power supply is to be started on basis of a difference in the start-up times between the elements. The directing unit is configured to direct a power supply unit for supplying power to the elements. The sending unit is configured to send the interrupt request.

    摘要： According to an aspect of embodiments, there is provided a random number generating circuit including at least one magnetic tunnel junction (MTJ) element and a control circuit. The MTJ element comes into a high resistance state corresponding to a first logical value and also comes into a low resistance state corresponding to a second logical value different from the first logical value. The control circuit supplies the MTJ element with a first current for stochastically reversing the MTJ element from the high resistance state to the low resistance state when the MTJ element is in the high resistance state, and supplies the MTJ element with a second current for stochastically reversing the MTJ element from the low resistance state to the high resistance state when the MTJ element is in the low resistance state.
