    摘要: A dynamic lookup table device and method for storing a plurality of function values, wherein each stored function value represents a value of a function evaluated at a selected domain point of the function's domain. The device generates an input address which identifies a domain point. In response to the input address, a memory device within the lookup table device provides a lookup table entry value. The memory device includes a plurality of storage locations for storing a plurality of lookup table values. It also includes a page table storage device for mapping each input address to a corresponding storage location. Each unallocated input address is mapped to at least one shared storage location containing a default lookup table value. Each allocated input address is mapped to a corresponding storage location allocated to the input address. If the lookup table entry provided by the memory device is the default value, the lookup table device determines the value of the function at the selected domain point. It then stores the function value in a storage location of the memory allocated to the input address. Toward this end, it first determines if the input address is allocated. If the input address is unallocated, a new storage location is allocated to the input address. The content of the page table storage device is then modified to map the input address to the new storage location.

    摘要: A virtual memory management arrangement translates a process virtual address of an item of data in an array of data into a physical address for use in accessing a memory. A virtual address translation portion forms, in response to a process virtual address, an array virtual address including a sub-array identifier identifying a sub-array in the array and an array virtual offset identifying a virtual storage location in the sub-array. A physical address translation portion forms, in response to the array virtual address, a physical address for use in accessing a memory.

    摘要: A user access security subsystem of a computer information database system utilizes computer grouping criteria and user type criteria to control user access to both computer profile data and system administrative features. Computer grouping criteria determine profile data access for the respective users. User type criteria determine which administrative features are accessible to the respective users, thus what administrative authority is delegated to the users. Combining computer grouping and user type criteria restricts a given user to exercising the delegated administrative authority only with respect to the particular grouping of computers to which the user has been granted access through the associated login group. To maintain access security, a given user may grant to another only those access rights that are equal to or more restrictive than the given user's rights. The subsystem enforces access restrictions by tailoring the user interface based on the associated login group and user type.

    摘要: A method of obtaining information about usage of application executable files and associated software program in a network of computers or on an individual computer is provided. The method involves collecting information about last use of software programs, and associated executable files, on a computer or a set of managed computers from various resources on the computers. The information that is collected includes file name, directory, date and time the executable was last started, a security identifier of the last user, the method of last use, whether the executable was found to be running at the time it was found, and whether the executable is registered to run as a service. From this information, a list is generated regarding software items, and the list is merged such that a given executable has a single software item on the list. Reports are produced detailing information about one or more software items on the list. The reports may be displayed in a graphic user interface designed for that purpose.

    摘要: Virtual address space for array data to be stored in a virtual memory is allocated by establishing a table that associates segments of the virtual address space with predetermined array data dimensions and maintaining a map that identifies, for each segment, which portions of the segment have been allocated to store array data. The table and map are used to identify a contiguous portion of the virtual address space for the array data to be stored.

    摘要: A display system for connection to a bus in a digital processing system having a system memory. The display system comprises a display memory, a display and an interface. The display memory stores image data. The display receiving stored image data from the display memory and generates in response thereto a displayed image. The interface receiving image data and address signals from the bus, the signals corresponding to addresses in the system memory. In response to the address signals, the interface determines whether the image data relates to image data for an image stored in said display memory and in response thereto controls storage of the image data in the display memory.
