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： A data interface mechanism for interfacing bit-parallel data buses of different bit widths. This mechanism provides an automatic and efficient mechanism for converting data bytes into plural-byte data words and vice versa. The mechanism utilizes a plurality of random access (RAM) storage units located between the two data buses and an addressing structure wherein the higher order address bits are supplied to a chip select decoder to produce different chip select signals which are used to select different ones of the RAM units. For successive data transfers to or from the narrower data bus, storage addresses are used which produce different chip select signals which select the different RAM units one after the other in a sequence which repeats itself. Thus, successive data bytes to (from) the narrower bus are transferred from (to) the different RAM units in a rotating manner. For data transfers to or from the wider data bus, a storage address is used which produces a distinctive chip select signal which is different from those used for the individual narrower transfers. This distinctive chip select signal causes the storage control logic to simultaneously select all of the RAM units. This enables a simultaneous parallel transfer of data from all of the RAM units to the wider data bus or vice versa.
