摘要： In a computer system having a central processing unit, a main storage and at least one I/O device, a plurality of operating systems (OS) can simultaneously run under the control of a control program. For executing an I/O instruction using a central processing unit, a plurality of resident areas of said main storage which do not overlap one another are assigned, under the control of the control program, to the plurality of OSs as main memories therefore, respectively. In responding to an I/O instruction issued by a running one of said plural OSs, an address of said main memory assigned to said running OS which participates in an I/Oo operation requested by said I/O instruction is determined without intervention of the control program, and the address is translated into an address of the main storage of the computer system without intervention of said control program. The I/O operation is then executed by using the address resulting from said address translation.

摘要： In a virtual machine system (VMS) capable of concurrently running at least one operating system (OS) under one real computer system and a control program (VMCP) for controlling the VMS, the object is to reduce the overhead produced for simulating VM I/Os by direct I/O execution. A VM information area of a real sub-channel control block has a status field in which a flag indicating that the sub-channel is dedicated or not is contained. When the flag is "0", it means that the sub-channel is dedicated to the VM and the sub-channel scheduling by the VMCP is not necessary. As a real interruption priority order is dedicated to a VM, only I/O interruption requests of the VM are queued into the real interruption request queue of that dedicated priority order, and the mixing of VMs in that real interruption priority order is avoided. When an interruption control mask of an interruption priority order of the OS on the VM is "0" indicating that the interruption is not acceptable by the VM, the interruption control mask of the corresponding dedicated real interruption priority order is also "0" and the hardware interruption does not take place. Accordingly, the interruption is retained by the hardware and the I/O interruption retention for the VM by the VMCP is avoided.
摘要翻译：在能够在一个实际计算机系统下同时运行至少一个操作系统（OS）的虚拟机系统（VMS）和用于控制VMS的控制程序（VMCP）的情况下，目的是减少模拟VM I / Os通过直接I / O执行。实际子信道控制块的VM信息区域具有包含表示子信道为专用的标志的状态字段。当标志为“0”时，这意味着该子信道专用于该VM，并且该VMCP的子信道调度是不必要的。由于真正的中断优先级顺序专用于VM，因此只有VM的I / O中断请求被排队到该专用优先级顺序的实际中断请求队列中，并且避免了该实际中断优先级顺序的VM的混合。当VM上的OS的中断优先级顺序的中断控制掩码为“0”，表示VM不能接受中断时，相应的专用实际中断优先级顺序的中断控制掩码也为“0”，并且硬件中断不会发生。因此，中断由硬件保留，并且避免VMCP对VM的I / O中断保持。

摘要： A plural-OS run system in which a plurality of operating systems (OSs) capable of operating on machines of different architectures, respectively, are allowed to run on one bare machine under the control of one control program (CP) or one control means. The input/output instruction and input/output interrupt of the operating system capable of running on a machine of the same architecture as that of the bare machine are directly executed on the bare machine without need for translation of the format. The input/output instruction and the input/output interrupt of the operating system adapted to run on a machine of the architecture differing from that of the bare machine are allowed to be directly executed while translating the format.

摘要： An address translation apparatus is provided which has an address translation look-aside buffer with an entry composed of a real address field, virtual machine identifier field and space identifier field. For the translation look-aside buffer entry to be used by a general virtual machine which uses a plurality of address spaces, a virtual machine identifier for discrimination of a general virtual machine is stored in the virtual machine identifier field, and information used in discriminating an address space is stored in the space identifier field. For the translation look-aside buffer entry to be used by a dynamic address translation off (DATOFF virtual) machine which uses a single address space, an identifier commonly assigned to a group of DATOFF virtual machines is stored in the virtual machine identifier field, and a control block address used in discriminating a DATOFF virtual machine is stored in the space identifier field.

摘要： A data processor has a first cache memory with a large capacity and one port and a second cache memory with a small capacity and two ports disposed between a main memory and an instruction processing section. Data which is frequently used is stored in the first cache memory and data which is less frequently used is stored in the second cache memory under control of a controller responsive to prefetch instructions. One of the cache memories may be a set associative cache memory composed of a plurality of memory chips each having at least two memory banks and an output part to gain access to data sets consecutively and one at a time within the memory banks. On the basis of an address sent from the instruction processing section, a memory bank is selected, and a data set from the selected memory bank is supplied to the processing section.

摘要： An information processor is capable of eliminating register conflict in short and long latency processes and for attaining high-speed pipeline processing through efficient use of registers. The scale of the necessary hardware is reduced by the processor using a register conflict detector and a scoreboard. The register conflict detector detects register conflict over a period of short latency processing, and the scoreboard checks for register conflict beyond the short latency process period and into a period of long latency processing. The processor controls the issue of instructions based on the detected register conflict status.
