    摘要： The functions of two virtual operating systems (e.g., S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated from 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors access the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

    摘要： A cycle steal mechanism for enabling a host processor to initiate and control the cycle stealing of data to or from a storage unit located in an I/O controller which is connected to the I/O channel bus of the host processor. The I/O controller also includes a microprocessor and a direct memory access (DMA) unit either or both of which can be used to control the transfer of data between the I/O controller storage unit and the host processor. Typically, the DMA unit is used for cycle stealing data between the controller storage unit and the host processor. The cycle steal mechanism of the present invention enables the host processor to also initiate and control the cycle stealing of data to or from the controller storage unit without interrupting the program running in the controller microprocessor and without interrupting the cycle stealing operations of the DMA unit. This new cycle steal mechanism is the reverse of the normal situation where it is the microprocessor or DMA unit that is controlling the cycle stealing. Since the I/O controller accommodates both kinds of cycle stealing, the present invention can be said to provide a "2-way" cycle stealing capability. Not only can the I/O controller cycle steal data to or from the host processor main storage unit, but also the host processor can cycle steal data to or from the I/O controller storage unit. The cycle stealing by the host processor is transparent to both the microprocessor and the DMA unit in the I/O controller. This new cycle steal mechanism makes use of the microprocessor address set-up pulse (ALE) and the DMA unit address set-up pulse (ADSTB) to cause the cycle stealing of the data to or from the controller storage unit to occur during such address set-up time. These address set-up times are times when neither the microprocessor nor the DMA unit is actually moving data into or out of the storage unit in the I/O controller.

    摘要翻译： 一种循环窃取机制，用于使得主机处理器能够启动和控制数据到位于连接到主处理器的I / O通道总线的I / O控制器中的存储单元的数据的周期窃取。 I / O控制器还包括微处理器和直接存储器访问（DMA）单元，其中一个或两者可用于控制I / O控制器存储单元和主机处理器之间的数据传输。 通常，DMA单元用于控制器存储单元和主处理器之间的循环窃取数据。 本发明的循环窃取机制使得主处理器能够启动和控制数据到控制器存储单元或从控制器存储单元的循环窃取，而不会中断控制器微处理器中运行的程序，而不会中断DMA单元的循环窃取操作。 这种新的循环窃取机制与正在控制循环窃取的微处理器或DMA单元的正常情况相反。 这种新的循环窃取机制利用微处理器地址设置脉冲（ALE）和DMA单元地址设置脉冲（ADSTB），使得在这种地址期间发生数据到控制器存储单元或从控制器存储单元的周期窃取 设置时间。
