Abstract: To provide an information processing device capable of improving manipulability for a user while efficiently displaying menus on a screen. Provided is an information processing device including: a detection unit configured to detect a position of a manipulating object; and a display control unit configured to cause a menu to be displayed on a screen according to the position of the manipulating object detected by the detection unit.

Abstract: An object is to suppress a process of evicting cached data so as to improve a throughput of an entire system. A storage controller includes an access request section and an operation management section. The access request section requests access to a first storage and to a second storage that is higher in response speed than the first storage, the second storage storing part of data stored in the first storage. The operation management section manages, based on a usage state of the second storage, whether or not to transfer from the first storage to the second storage data targeted for access but not stored in the second storage.

Abstract: Even data mapped to discrete physical addresses of a volatile memory is saved in a non-volatile memory. A memory management information registration unit registers, as an entry of memory management information, a physical address of a first memory that is volatile memory and an address of a second memory that is a non-volatile memory, in association for every management unit. A control unit saves data from the first memory into the second memory in accordance with the memory management information in response to a save request, and restores data from the second memory into the first memory in accordance with the memory management information in response to a restore request.

Abstract: Memory devices having different parallel accessible data sizes and different access speeds are caused to work efficiently as a cache memory. A memory access device accesses first and second memory devices that respectively include a plurality of parallel accessible memories and have different parallel accessible data sizes and different access speeds. The memory access device includes a management information storage unit and an access control unit. The management information storage unit stores management information as associating each corresponding management unit of the first and second memory devices. The access control unit accesses one of the first and second memory devices on the basis of the management information.

Abstract: Provided is an information processing device including: a detection unit configured to detect a position of a manipulating object, and a display control unit configured to cause a menu to be displayed on a screen according to the position of the manipulating object detected by the detection unit. The display control unit causes, when the detection unit detects that the manipulating object is positioned on a first icon serving as a base point, one or more second icons corresponding to a main menu to be opened and displayed, and causes, when the detection unit detects that the manipulating object is positioned on one of the second icons, one or more third icons corresponding to a sub-menu subordinate to the main menu to be opened in a direction orthogonal to an opening direction of the second icons and displayed by using the selected second icon as a base point.
