摘要:
Mask data in a PSW are latched and sent from a host to a guest are subjected to a logical AND operation with latched data taken from an intervention request field of a state descriptor of the guest machine. The resultant logical product is used for setting the PSW of the guest machine and activating an interception to the host. The overhead of an execution controller managing the state transition between guest-host machines is reduced.

A data processing system includes a multistage pipeline arithmetic/logic operation unit for implementing an arithmetic or logic operation for sets of element data sequentially and storing operational results sequentially in a memory using a single instruction. Check information indicative of the presence or absence of a fault occurring in each stage of the pipeline operation unit is moved in synchronism with the advancement of stages of the pipeline operation unit. A request control unit for storing the operational result in the memory suppresses the storing of the operational result in the memory if check information indicates a fault of the operational result which is being stored in the memory. The request control unit issues storage requests, which are counted by a counter. The counter indicates the number of elements stored normally in the memory.

A vector data processor includes a vector data buffer for receiving a plurality of arrayed data items requested from a storage including a plurality of storage banks (banks-0-3 in FIG. 2) for independent operations. The vector data buffer is constructed of a plurality of bank memories which conform to a corresponding periodic relationship between the arrayed data items and the storage banks. Date storing areas for storing the arrayed data items are preset on the successively different bank memories of the vector data buffer in the sequence in which the individual arrayed data items have been requested. The individual storage banks in the sequence in which the arrayed data items have been requested are respectively connected to the successively different bank memories, and the arrayed data items fetched from the individual storing banks are stored in the connected bank memories in succession.

A computer system operable as a virtual machine system capable of accessing multiple virtual address spaces, which has an access register translation means for translating a space identifier into an origin address of a table for address translation and a translation pair memory for storing translation pairs of the space identifiers and the associated origin addresses. In each entry of the translation pair memory, a field is provided in association with the translation pair, for storing a machine identifier of the guest virtual machine associated with the translation pair. When accessing a virtual address space, a guest virtual machine makes reference only to the associated translation pair based on the virtual machine identifier thereof.

摘要:
A guest execution control system method and computer process for a virtual machine system having a main storage for holding a state descriptor of a guest virtual machine, and a plurality of instruction processors each starting execution of the guest virtual machine by executing an execution start instruction for the guest virtual machine. Execution instruction information in the state descriptor indicating whether execution of the guest virtual machine is to be finished is changed when a state of the virtual machine satisfies a predetermined condition during execution of the guest virtual machine. The execution instruction information is held at an address in the main storage. The guest execution control system includes a circuit which compares an address in the main storage of information being changed with the address in the main storage of the execution instruction information, and informs the guest virtual machine being executed that the execution instruction information has been changed when the address in the main storage of information being changed is the same as the address in the main storage of the execution instruction information. The guest execution control method and computer process performs the comparing and informing operations for the virtual machine system.
摘要:
A data processing system capable of accessing multiple virtual address spaces wherein a an access register translation is performed when obtaining an origin address (STO) of a translation table to be used for address translation of a logical address into a real address. If an access register designated by an instruction has a value equal to a predetermined value, another STO stored in a control register is used instead of the STO obtained by the access register translation. Registers are provided for storing results of detection as to whether or not each of the access registers has a value equal to the predetermined value and a sector is provided selecting either the STO in the control register or the STO obtained by the access register translation based on the stored results of detection, thus eliminating a process to discriminate the values of the access registers at each access to the virtual address spaces.
