摘要： A data processing apparatus for an address boundary check circuit employed in combination with a virtual storage (500) comprises a segment table register (40) provided in association with an address translation table (800) for storing an area discriminating signal (P) indicating whether data to be checked in respect to the address boundary is assigned to unit areas (750, 75l, 752) resulting from division of the virtual storage and holding a limit address signal (UA) indicating the extent of the area assigned to data which requires an address boundary check of a virtual address accessing the data when the data is found in that area, a register (787) holding a virtual base address for storing a register discriminating signal (L) indicating whether or not the base address is for data to be checked in respect to the address boundary, and an address boundary check circuitry (l000) for deciding on the basis of the aforementioned first to third signals whether or not a virtual address calculated in response to an instruction (770) erroneously goes beyond the address boundary.

摘要： In a real storage allocation method, a real storage containing a plurality of real pages to which storage keys used for a storage protection purpose should be stored is allocated to a plurality of virtual pages of a virtual storage in accordance with the real pages. The real storage allocation method includes the steps of: (a) allocating one of plural split regions each having a first size which is obtained by subdividing one of plural real pages each having a second size equal to a value "n" ("n" being a positive integer) times higher than the first size, and which is provided with the real storage, to one virtual page having the first size employed to the virtual storage, and (b) repeating the step (a) in such a manner that one of plural split regions each having a first size which is obtained by subdividing other split regions within the one real page, or other real pages having the second sizes, is allocated to other virtual pages having the first pages. Furthermore, the real storage allocation method includes the steps of: (c) among a plurality of first sort of virtual pages each having a first size and a plurality of second sort of virtual pages each having a second size 1/n ("n" being a positive integer) times the first size, which have been previously prepared, when the real storage is allocated to the first sort of virtual page, allocating to the first sort of virtual page, a real page group constructed of one of the first sort of real pages, or "n" pieces of the second sort of continuous real pages which have not yet been allocated to the virtual page among a plurality of first sort of real storages each having the first virtual pages previously employed in the real storage and also a plurality of second sort of real pages each having the second size; and (b) when the real storage is allocated to the second sort of virtual page, allocating one of "n" pieces of split regions obtained by dividing one of the first sort of real page, or one of the second sort of real page.

摘要： In order to perform format conversion between the formats of a plurality of files without any work by a user, a file system (100) stores a relation between a conversion originating file (130) and a conversion destination file (131), and synchronously with an issue of a file operation API, the format conversion processes are executed. A user performs only the tasks essential for an application, without taking into consideration various necessary format conversions (either one-step or multi-step). During the user task, it is not necessary to designate a conversion originating file and a timing of format conversion. A user can use always a latest conversion destination file.

摘要： A main storage management process in a computer system which executes a program in a multiple manner under control of a virtual storage type operating system. A first portion area of a real storage area (103), allocated to a first program and used later is maintained in that state while the contents of a second portion area of the real storage area is saved in an auxiliary storage (104) to release the second portion area when the first program is to be released. The saved contents of the second portion area from the auxiliary storage (104) is loaded on the real storage (103) when the first program is to be swapped in.

摘要： A data processor of this invention specifies (16,17) either of a predetermined maximum length of an address (a bits) and the length of an address less than the former length and at least one register (7) having the number or length of bits of the maximum address length or greater (r bits). The data processor reads out lower-order d bits of said at least one register (7) specified by a first instruction to perform arithmetic operations, and writes the arithmetic result into a register element contained in said at least one register (7). Moreover, the processor reads out bits from a register element contained in said at least one register (7) specified in a second instruction to generate an a-bit address, and reads out d bits from a storage device (5) in response to the thus-generated address to write the d bits into either the storage device (5) or said register element.
Accordingly, since the data length is consistently d bits irrespective of specified effective length of an address, direct data transfer is enabled between programs each having a different effective length of an address. Facilitating extension of the length of a storage address and assuring compatibility with conventional data processor.
摘要翻译：本发明的数据处理器规定（16,17）地址（比特）的预定最大长度和小于前一长度的地址的长度，以及至少一个具有数字或长度的寄存器（7）最大地址长度或更大的位（r位）。数据处理器读出由第一指令指定的所述至少一个寄存器（7）的低位d位以执行算术运算，并将算术结果写入包含在所述至少一个寄存器（7）中的寄存器元件。此外，处理器从包含在第二指令中指定的所述至少一个寄存器（7）中的寄存器元件读出比特以产生一个比特地址，并响应于该存储设备（5）从存储设备（5）读出d个比特由此产生的地址将d位写入到存储设备（5）或所述寄存器元件中。因此，由于数据长度与地址的指定有效长度无关，始终为d位，因此在每个具有不同地址有效长度的程序之间启用直接数据传输。有助于延长存储地址的长度，并确保与传统数据处理器的兼容性。
