    Abstract: The disclosure relates to an improvement to an information processing system for conducting data processing operations wherein the processing relates to the value of the information and conducting text processing operations wherein the processing affects only the format of information. The improvement provides the combination of means for initiating a data processing session in said system, means for switching to a text processing session before the completion of the data processing session, means for storing the status of the non-completed data processing session during the text processing session, and means for switching back from the text processing session to the non-completed data processing session.

    Abstract: DEPTH BUFFER CLIPPING FOR WINDOW MANAGEMENT In a computer system having a display adapter, a refresh buffer and an interactive display terminal with a screen display on which is formed a plurality of at least partially overlapping windows, a depth buffer is added to the display adapter for providing clipping assistance to the software-based window manager in the CPU. The window manager is programmed to monitor the current depth position of each of the plurality of windows. In response to an input request for a rearrangement of the windows, the window manager assigns a new depth value to the subject matter associated with each affected window and requests that each application retransmit at least the affected subject matter. The depth buffer includes an array which stores the depth values of the subject matter associated with each of the windows being currently displayed on the screen. In response to the rearrangement request, depth buffer receives the new depth values for the subject matter associated with each affected window from the window manager and compares the current depth values. If the comparator determines that the new subject matter has a depth value associated with the same window or a window closer to the viewer, the depth buffer notifies the refresh buffer to store the newly transmitted subject matter from each of the applications being run on the CPU. In an alternative embodiment, two buffers are used to store the depth information associated with the subject matter in a window, i.e. a W-buffer to store the depth of each window relative to a reference point and a Z-buffer to store the depth of the subject matter within a window.

    Abstract: VIRTUAL MEMORY ADDRESS TRANSLATION MECHANISM WITH COMBINED HASH ADDRESS TABLE AND INVERTED PAGE TABLE A virtual memory address translation mechanism is provided for converting virtual memory addresses provided by a CPU into real memory addresses within page frames in a large hierachial memories wherein the real memory space is substantially smaller than the scope of the virtual memory. The conversion or translation mechanism includes a combined table in the memory which includes a first list covering the respective virtual address of each memory address (Inverted Page Table or IPT) and a second list connecting each of a plurality of hashed addresses with a predetermined initial virtual address of a linked group of virtual addresses, each of which when hashed produces the connected hashed address (Hashed Addressed Table, HAT). The system also has means for hashing a selected virtual address to produce a hashed address. Also included is apparatus for sequentially searching through the linked group of virtual addresses in the combined table until a selected virtual address is located as well as apparatus responsive to the location of a particular selected virtual address for accessing from the first list, the real memory address of the located virtual address.
