摘要： PROBLEM TO BE SOLVED: To arrange a program area in arbitrary actual addresses and to effectively use a storage device by providing a means which performs arbitrary branching from an address to an arbitrary address on a main storage device by specifying an address of a virtual storage.
SOLUTION: A field storing SCD used for extension address conversion of an instruction address is provided in PSW 101. Here, a storage location may be a control register or ASTE. When a branch instruction is executed, a CPU updates the instruction address field in the PSW 101 to the virtual address of a branch destination and also updates the SCD field in the PSW 101. The value of the SCD field is switched before or after the branch instruction, so branching even to a location arranged in a different section on the actual storage device is possible. As the branch instruction is executed, the value of the SCD field provided in an SGT entry 105 is copied as a value stored in the SCD field in the PSW.

摘要： PURPOSE:To maintain a high cooling effect for an electromagnetic coil, ensure the high operation rate and performance thereof and make a device compact by applying an insulation of extremely high insulation resistance to a bobbin surface, and reducing thermal resistance between a coil and a cooled copper bobbin. CONSTITUTION:A copper spring coil 1 is pressed with a water cooled copper bobbin 4 at both edges and fixed with set bolts. In this case, an insulation thin film layer 3 for the edges of the coil 1 and the bobbin 4 is made a few mum thick to lower thermal resistance between the coil 1 and bobbin 4, and an insulation layer of extremely high resistance is applied to the surface of the bobbin 4. Also, the copper spring of the coil 1 is, for example, 0.2mm thick and 20mm wide, and turned by the predetermined number. In addition, the surface of the coil 1 is applied with an insulation thin film, thereby maintaining insulation between copper spring layers. Also, the coil 1 is independently integration molded with epoxy resin 6 or the like, and solidified. In addition, parallelism between both edges of the coil 1 and the surface thereof are properly maintained or polished to be smooth, and bare copper is exposed at the edges. According to this construction, a high cooling effect can be ensured, and an operation rate can be enhanced. Also, high performance can be ensured, and a device can be made compact.

摘要： PURPOSE: To provide a fault information sampling method which supports the analysis of a fault factor by providing a step to designate the inquiry of a fault content when fault information is sampled and a step to sample the fault information as holding the state of an address space. CONSTITUTION: When abnormality occurs in an operating system provided with multiplex virtual storage function, an input means 2 informs the fault acceptance means 1 of the fault information managing program of an OS of it. The fault acceptance means 1 performs the confirmation and inquiry of the fault content from the input means 2 via the input means 2, and delivers the fault content to a fault judging means 3. The fault judging means 3 judges an inputted fault content and the state of the system, and decides a fault sampling method, and delivers it to a fault information sampling process 4. The fault information sampling process 4 outputs the fault information to a fault information output device 5, and uses it as the input information of an analyzing means 6 for fault factor. In this way, when the abnormality such as the one in which despatch is disabled after a job is executed, etc., occurs, the fault information is sampled as holding job information.

摘要： PROBLEM TO BE SOLVED: To execute a conventional program and to maintain the transferability of the program by checking whether the size of a loaded real address is larger than that of a virtual address by comparison and making an interrupt occur. SOLUTION: An addition circuit 10 adds a base register number 560 designated by the 2nd operand of an instruction 100 requiring a real address, an index register number 570 and displacement 580 to calculate a virtual address 600 of a 31-bit size. A real address of a 31-bit size in a section is calculated by combining a page number 930 and a displacement field 630 of the address 600. A real address expansion mode flag 202 is compared with a section identifier 920. When the flag 202 is off and also, the identifier 920 is not zero, a program interrupt is made to occur, a
