Abstract: A communication terminal or system is provided with a processor that calculates a transmission data size that is suitable to a detected state of a network, and analyzes contents of image data for transmission to determine an image parameter that should be prioritized. The communication terminal or system encodes the image data for transmission into encoded image data, based on the calculated transmission data size and the image parameter that should be prioritized.

Abstract: Management of a process having a kernel mode and a user mode and executed on an operation system is performed by receiving a request for moving to a user system mode from a user process, and changing the user process into a kernel mode in response to the request.

Abstract: An apparatus, method, system, computer program and product each capable of managing memory in a virtualization system. A selected page of an operating system is loaded into a physical memory when an attempt to access the selected page is detected.

Abstract: A multifunctional apparatus includes a hardware resource, a plurality of functional systems, and a hypervisor. The hypervisor partitions the hardware resource into a plurality of logical partitions and allocates the plurality of logical partitions respectively to the plurality of functional systems.

Abstract: The information processing apparatus reserves a direct mapping region in the physical memory space and correlates physical addresses of the direct mapping region in the physical memory space with the virtual addresses of the virtual memory region in the virtual memory space of a process. Accordingly, the number of exception errors caused by the address translating unit is reduced, and the overhead on memory accesses is reduced.

Abstract: An information processing apparatus that uses a virtual memory function for executing a program is provided. The information processing apparatus includes: a file management part for managing a file in a read-only memory; a table generation part for generating a table in which a physical address of the program in the file in the read-only memory is associated with a virtual address of the program; a program execution part for obtaining the physical address of the program in the read-only memory by using the table from the virtual address of the program so as to execute the program on the read-only memory.
