摘要： A storage unit comprises a plurality of storage modules, each of which is dynamically assigned to and used as each area in a main storage (MS) or an extended storage (ES). The storage unit or a system controller has address arrays for MS and for ES which store information indicating which of the storage modules comprised in the storage unit each area in the MS and the ES corresponds to. When the contents of the MS/ES address arrays are rewritten to change a storage module belonging to the ES to a storage module belonging to the MS, a page-in operation is realized without executing an actual data move operation. Similarly, a page-out operation is realized without executing an actual data move operation by changing a storage module belonging to the MS to a storage module belonging to the ES.

摘要： A level-2 virtual machine is constructed under the control of a level-1 operating system (OS) operating on a real machine (level-1), and a level-3 virtual machine is constructed under the control of another operating system (OS) operating on the level-2 virtual machine. A level-3 virtual address generated in the level-3 virtual machine is translated to a level-2 virtual address, which is further translated to a level-1 virtual address. A third predetermined main storage address is added to the level-1 virtual address to generate a level-1 absolute address. The translated address is checked as to whether it is within a predetermined area on the main storage.

摘要： A method fr purging a translation lookaside buffer purges only those entries required to be purged in order to eliminate overhead incurring degradation in the use efficiency of the translation lookaside buffer. The buffer is employed in a virtual machine system containing a plurality of levels of virtual machines and at least one register for storing virtual machine identification codes. Upon execution of an instruction, which is issued by a particular one of the virtual machines and which is accompanied by a purge of the translation lookaside buffer, the virtual machine identification code of the particular virtual machine and a virtual machine identification code of another virtual machine having a translation lookaside buffer entry to be purged are stored in the register. When the instruction is executed, the entry storing the virtual machine identification code which coincides with that of the particular virtual machine is purged, while the entry storing the virtual machine identification code which coincides with that of the other virtual machine is purged in parallel.

摘要： A data processing apparatus for performing decimal arithmetic operation with the aid of a decimal arithmetic unit having an operation width corresponding to a plurality of bytes. Length value of an operand which is to undergo arithmetic operation of the decimal arithmetic unit is held in an operand length register, while a byte position which constitutes the least significant position in the arithmetic operation is held in an operand point register. An overflow detection controlling circuit generates a control signal in accordance with the contents in both the registers. An overflow detecting circuit detects presence or absence of an overflow by checking a particular byte contained in the output of the decimal arithmetic unit, the particular byte being designated by the control signal produced from the overflow detection controlling circuit.

摘要： An armor cabinet of a projection type display unit includes a base cabinet on which main component parts are mounted, and a top cover made from sheet metal which is mounted so as to cover the base cabinet, wherein a rear face portion composed of the top cover is formed in the shape of a curved surface being laid-down U-shaped in side view. At the time of carrying the projection type display unit, the rear face portion in the U-shaped curved surface shape is just fitted to the palm on an ergonomic basis, and the grip can range to the fingertips, so that the rear face portion can be gripped assuredly and securely even with one hand. On the back side of the top cover, bosses are integrally formed by use of a resin which is a different material from the sheet metal of the top cover, and the base cabinet and the top cover are fixed by fastening screws to the bosses from the base cabinet side.
