To provide a memory protection circuit and a memory protection method suitable for quick data transfer between a plurality of virtual machines via a common memory, according to an embodiment, a memory protection circuit includes a first ID storing register that stores therein an ID of any of a plurality of virtual machines managed by a hypervisor, an access determination circuit that permits the virtual machine having the ID stored in the first ID storing register to access a memory, a second ID storing register that stores therein an ID of any of the virtual machines, and an ID update control circuit that permits the virtual machine having the ID stored in the second ID storing register to rewrite the ID stored in the first ID storing register.

Memory protection circuit and memory protection method

An operation system for a vehicle includes a memory, and a processor coupled to the memory and configured to acquire a first signal indicating whether a seat in the vehicle is facing forward or rearward, and generate a display screen by arranging at least two operation elements in a longitudinal direction of the vehicle. The display screen is displayed on an operation panel installed in the vehicle. The processor reverses the arrangement of the at least two operation elements in the longitudinal direction of the vehicle in accordance with the first signal.

The navigation device includes a detour exploring portion configured to explore a detour to avoid a section in which a traffic hazard occurs using map data at a level lower than a predetermined level when a traffic hazard determining portion determines that the traffic hazard occurs on the guidance route, and a display control portion configured to zoom the detour to match a scale of the detour to a currently designated scale, and synthesize and display the detour on a map image. The navigation device maintains the display of the wide area map and synthesizes and additionally displays a detour, for example, to pass through a road such as a narrow street included in a detailed map on the map image such that the user can receive, at a glance, a detour to easily bypass the section in which a traffic hazard occurs.
