The time required for transition from an on-state to a suspend state is reduced. An electronic apparatus includes: a memory and a memory; a current control unit that performs a control to shut off supply of current to the memory; and a memory management unit that allocates a memory region in either the memory or the memory based on preference information indicating a memory region that needs to be preferentially allocated in the memory. For example, the preference information includes association with a first priority as a degree at which a memory region to be used by an application needs to be preferentially allocated in the memory, and when receiving a request of allocation of the memory region from the application, the memory management unit more preferentially allocates the memory region in the memory as the first priority associated with the application in the preference information is higher.

A virtual machine system includes one or more virtual machines and a deactivator that deactivates the virtual machines. Each virtual machine includes an output unit that outputs a deactivation prohibiting signal indicating that the virtual machine is not permitted to stop operating while deactivation prohibited processing is being executed. The deactivation prohibited processing is processing that involves the device and during which the virtual machine is not permitted to stop operating. The deactivator deactivates a virtual machine that has not output the deactivation prohibiting signal, and does not deactivate a virtual machine that has output the deactivation prohibiting signal.

A virtual machine system for duplicating a first virtual machine to generate one or more second virtual machines is provided with a management unit that manages each memory area accessible by the first virtual machine so that after generation of the second virtual machines, every virtual machine is permitted to perform a read access to the memory area until any virtual machine performs a write access to the memory area, a determination unit that determines whether each memory area is a specific memory area, a detection unit that detects, after detecting a write access to a specific memory area, that a virtual machine other than the virtual machine performing the write access is attempting access to the specific memory area, and a memory allocation unit that acquires and allocates a new memory area to the virtual machine detected to be attempting access to the specific memory area.

In one embodiment of a print system, a client terminal () that generates a print job, a server function portion that stores the print job, a printer () that performs pull printing of the print job are connected via the network (). The print job holds print data and authority information including user information for specifying a user having print authority over the print data. The client terminal () is provided with an authority setting means for setting authority information. A server () is provided with the server function portion, and is configured to update authority information, identify a user, authenticate whether or not to permit printing based on the authority information and the identification result obtained by a user identification means, and transmit print data.

An execution binary image creating device includes an execution binary reading section (1) reading configuration information representing an internal configuration of an execution binary program to be executed on a computer and includes a deletable area detecting section (2) acquiring the configuration information of the execution binary program, analyzing information to be used in performing address resolution at a time of execution, and detecting a deletable area in the execution binary program, when the address resolution is not performed. Further, the device includes an execution binary rewriting section (3) rewriting the deletable area in the execution binary program into specific data and using an execution binary image creating section (4) reducing the data amount of the specific data included in the execution binary program, and converting the execution binary program into an execution binary image in a format recognizable on the computer.

A process scheduling apparatus has a delayed task handling process for processing delayed tasks having variable priorities and multiple other processes for handling processes other than delayed tasks. Fixed priorities are assigned to the other processes. The process scheduler sequentially executes the delayed task handling process and the other processes according the assigned priorities. A delayed task registration processor stores newly generated delayed tasks with assigned priorities in a queuing table. A delayed task priority controller selects the delayed task with the highest priority in the queuing table. A process priority controller sets the priority of the delayed task handling process to the same priority as the priority of the delayed task with the highest priority.

A power-saving processing unit is provided which is capable of realizing proper mode switching by taking into account a power consumption as well in a shift processing and a return processing for switching an operation mode. In a power-consumption information table, there are recorded a power consumption (mJ) which is required for a processing for shifting into a power-saving mode, a consumed power (mW) when an operation is executed in the power-saving mode and a power consumption (mJ) which is required for a processing for returning to an ordinary mode. A time prediction sectionrefers to a timer-list management queueand predicts a period of time until the power-saving mode is removed. On the basis of the power-consumption information tableand the predicted time, a mode-switching decision sectioncompares a power consumption (mJ) when switching is executed into the power-saving mode and a power consumption (mJ) when the switching is not executed, and only if the former is far less than the latter, decides that switching should be executed into the power-saving mode.

A device information administrator detects a fluctuation in a total consumed power of a power-consuming device group and determines and outputs a consumed power to be changed by any of devices in the power-consuming device group so as to suppress this fluctuation. A power-save determinator generates and outputs a control command for at least one device of the power-consuming device group so that the total consumed power of the power-consuming device group changes in accordance with the consumed power to be changed outputted from the device information administrator. A device controller controls at least one device corresponding to the control command outputted from the power-save determinator in accordance with the control command. Accordingly, the fluctuation in the total consumed power of one or more power-consuming devices can be effectively suppressed.

To start up an operating system (OS), CPU performs initializations in three modes: The three modes include a first I/O initialization (Early init) () which is to be done serially when no threads are yet usable, without any advanced technique and with a long wait time until a next operation can be made; a second I/O initialization () which is to be done when threads are usable, in a plurality of steps parallelized with each other using the usable threads according to the dependency relation between devices to be initialized and with synchronization between the steps each by a barrier; and a third I/O initialization (Lazy init) () in which remaining initializations are done in parallel with each other using the threads commensurately to a user process when the user process becomes executable. The present invention is applicable to home-use electric or electronic appliances.
