In a disclosed embodiment of the address space control apparatus, each general-purpose register usable as a base register is associated with another general-purpose register in addition to an access register containing a segment table origin. When a general-purpose register is selected as a base register, the contents of its associated general-purpose register are read out and added to the segment table origin from the associated access register to provide an effective segment table origin. In a modification, the access registers are omitted, and the general-purpose register selected as a base register are used to select an entry in a register or register array containing segment table origins in respective entries. In other embodiments disclosed, general-purpose registers are used in different manners to enhance virtual address space control functions.

In a memory hierarchy system having two or more hierarchy storages of different access speeds and programs and/or data to be loaded on the hierarchy storages, an activity information acquisition unit and a display unit are provided to present information regarding selection of programs and/or data to be loaded on a higher level in memory hierarchy, a unit is provided which automatically decides loading of the programs and/or data on the higher level and executes reallocation of the programs and/or data on the basis of the information, and a unit is provided which permits the user to change the loading by using a user command. The user can make full use of these units during execution of the memory hierarchy control. In an embodiment, priority for the programs and/or data to be loaded on the higher level is calculated and decided. The programs and/or data are written into the real storage in accordance with their priority to increase the real storage hit rate upon occurrence of a next request for loading.

An area boundary between a system common area and a job private area is set at any page boundary independently from a segment boundary, and for the segment (boundary segment) containing the area boundary, a page table is prepared for each virtual address space. Thus, virtual pages which are not used as the system common area in the bondary segment can be used by jobs as job private areas.The real page is fixedly allocated to the virtual page belonging to the system common area in the boundary segment. Thus, it is not necessary to simultaneously update page tables for the system common area. Those virtual pages may be subjects of dynamic allocation of the virtual storage.

A vehicular travel control device according to the invention includes an inter-vehicle distance measuring section that is mounted on a subject vehicle and measures an inter-vehicle distance between the subject vehicle and a preceding vehicle, a target inter-vehicle distance setting section that sets a target inter-vehicle distance, a following travel control section that performs a travel control so as to make the inter-vehicle distance become equal to the target inter-vehicle distance and stops the subject vehicle while following a stopping of the preceding vehicle, a gradient acquiring section that acquires a gradient of a road being traveled of the subject vehicle, and a vehicle speed sensor that measures a travel speed of the subject vehicle. The target inter-vehicle distance setting section sets the target inter-vehicle distance based on the gradient and the travel speed.
摘要:
A first server including a local disk and a second server are logically partitioned by virtualization units. The first and second servers each have a storage controller LPAR with a local disk sharing function running thereon. The storage controller LPARs running on the first and second servers communicate with each other. When a disk I/O command issued by the second LPAR running on the second server is transferred to the local disk of the first server, the second LPAR reads data stored in the local disk or writes data thereto. In this way, the local disk is shared.

When a start-up operation by a driver is detected while a vehicle is maintained at a stopped state, a target driving force for suppressing the movement of the vehicle on the road to be driven is calculated, based on the grade obtained regarding the road to be driven on. After the vehicle is driven by the target driving force, the braking force is released so as to terminate the maintaining of the stopped state of the vehicle. Preferably, the state of being driven by the target driving force is maintained until the releasing of the braking force is completed. When the releasing of the braking force is completed, the driving force is increased to start-up the vehicle. With such a start-up control, vehicles are prevented from moving temporarily in a direction opposite from the traveling direction, and a smooth star-up can be achieved.
