Abstract: In order to ensure that a normally-off computer connected to a volatile component operates normally and rapidly after operation of turning-on/off of a power supply is executed, a computation processing device which has nonvolatile registers and which is able to continue processing of data retained in the device after the power supply is turned off/on without retracting the data to an external device includes at least: a central processing unit including the nonvolatile registers; a connection unit for a volatile component which saves internal information in a volatile storage element thereof; a nonvolatile storage unit for saving a return program from a power-off state of the volatile component; and an inspection unit notifying that a potential of the power supply in the computation processing device has reached an operation potential at a time of return.

Abstract: The QoS levels of multiple tasks are maintained at equal levels by executing items of the tasks stored in a queue during a given time interval at respectively adaptively controlled CPU utilization rates. The QoS levels of the executed items are detected and evaluated. The CPU utilization rates are updated with respective differences between a target value and the evaluated QoS levels. A difference is detected between each of the evaluated QoS levels obtained during a previous time interval and each of the evaluated QoS levels obtained during a current time interval and the detected difference is compared to a predetermined value. During a subsequent time interval, the previously stored items of the queue are replaced with new items of the tasks if the difference is smaller than the predetermined value and the previously stored items are executed again with the updated CPU utilization rates if the difference is greater than predetermined value.
