    • An ECL output circuit comprises a current switching circuit of the differential circuit type including a first transistor having a base connected to receive an input voltage and a second transistor having a base connected to a first reference voltage. A third transistor of an emitter follower has a base connected to a collector of the second transistor and an emitter connected to an output terminal. There is also provided an output level detection and feedback circuit including a differential circuit composed of fourth and fifth transistors having their emitters connected in common to a constant current. The fourth transistor has a base connected to the output terminal and a collector connected to the common-connected emitters of the first and second transistors. The fifth transistor has a base connected to a second reference voltage which determines a low level voltage of an output voltage. A sixth transistor is connected in parallel to the fifth transistor and has a base connected to receive the input voltage. Thus, it becomes unnecessary to lower the low level voltage of the output voltage, and the operating margin is not reduced. In addition, a high switching speed can be obtained.

    • 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.
    • 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。

    • A time-switch circuit for use in a primary time switch (PTSW), a secondary time switch (STSW), and a space switch (SSW) of a digital time-division switching system is disclosed. The time switch comprises a plurality of memory circuits (MUC.sub.11 to MUC.sub.15, MUC.sub.21 to MUC.sub.25). Each memory circuit comprises a memory unit (MEM), an address buffer (AB) for a first address, an m-ary counter (T-CTR) for a second address, an address selector (AS) for selecting either the first or second address, an input data buffer (IB), and an output data buffer (OB). In a write cycle, input data from the input data buffer is written into the memory unit by either the first or second address signal, and in a read cycle, output data is read out of the memory unit by either the second or first address. Selection of the first and second addresses is performed by the address selector, which is controlled by an address-selection mode switch circuit (M.sub.0). Further, the write enable mode of the memory unit is controlled by a write mode switch circuit (M.sub.1).
