摘要： In a memory system having a storage device and a key storage keeping key data controlling an access to the storage device, there is disposed a key address translation structure for obtaining an address of an entry of the key storage based on an address of the storage device to which an access request is issued. As a result, when subdividing the storage device according to the key data setting unit, each subdivided area can be assigned with a variable size and a plurality of sizes are enabled to be specified for the key data setting units at the same time.

摘要： A file sharing method and system for a multiprocessor system has an auxiliary storage unit that is shared in use by a plurality of processors each adopting virtual storage management. An auxiliary page table for storing on a page-by-page basis addresses of files contained in the auxiliary storage unit is prepared on a main storage provided for each of the processors. In response to a file map request issued by a program, an address of the file stored in said auxiliary storage unit is stored in the auxiliary page file. When the file is not stored in the main storage, a page exception interruption occurs, in response to which the address of the file stored in the auxiliary page table is referenced to for thereby transferring the file to the main storage from the auxiliary storage unit. The file stored in the auxiliary storage unit is transferred in the state undergoing an exclusion control.

摘要： An information processing system managing a virtual memory by using a real memory system comprising a single or a plurality of processors which, when a real page allocation request occurs in a processor or task keeping the use priority that the real pages of a group among the divided groups of the real pages of said memory can be used in a priority basis, allocated the real pages belonging to said group for which said processor or task keeps the use priority to said processor or task in a priority basis so as to decrease the cache cancel rate and the mapping fault occurrence rate and to allow for smoothing and high speed access of the main memory.
摘要翻译：一种信息处理系统，其通过使用包括单个或多个处理器的实际存储器系统来管理虚拟存储器，所述处理器当处理器中发生真实页面分配请求时，保持使用优先级，使得分组中的真实页面所述存储器的真实页面的组可以优先使用，分配属于所述组的实际页面，所述组的所述处理器或任务将所述处理器或任务的优先级按优先级保持在所述处理器或任务上，以便减少缓存取消速率和映射故障发生率，并允许主存储器的平滑和高速访问。

摘要： 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.
摘要翻译：系统公共区域和作业专用区域之间的区域边界被设置在独立于段边界的任何页边界处，并且对于包含区域边界的段（边界段），为每个虚拟地址空间准备页表。因此，不用作债券部门中的系统公共区域的虚拟页面可以由作为作业私人区域的作业使用。真实页面被固定地分配给属于边界段中的系统公共区域的虚拟页面。因此，不需要同时更新系统公共区域的页表。这些虚拟页面可以是虚拟存储器的动态分配的主题。

摘要： 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.
