    Abstract: As the speed and capacity of graphics workstations and personal computers including graphics adapters increases, a display adapter which can be used either in such a high capacity stand alone graphics workstation or in conjunction with a large main frame host computer includes a first processor for managing adapter resources and controlling coordinate transformations; a system storage for storing instructions and data representing information to be displayed; a first-in, first-out input buffer for allowing asynchronous and overlapped communication between the graphics system and a host computer;a second processor for drawing vectors and manipulating areas to be displayed on the monitor;a frame buffer connected to the second processor for storing a bit map of data to be displayed; a colour palette connected to outputs of the frame buffer for providing appropriate colour signals to the monitor; and a hardware cursor circuit for controlling display of a cursor on the monitor.

    Abstract: A full page display device for a text processing system in which a text stream input by way of a keyboard is stored and displayed to the operator on a display device including a cathode ray tube, the electron beam of which is modulated and scanned in a series of horizontal traces to produce an image of the text line on the screen of the display device. The system comprises storage means which includes a plurality (four in a specific embodiment) of separate storage devices (47-54). In the specific embodiment, when the storage devices are accessed for display, one character is accessed simultaneously from the same location in each of the storage devices. The data is latched and coupled to a character generator (36) to read out character dot pattern data which is latched and then interleaved with the data from other accessed character data by transferring the data one character at a time in parallel to a serializer (70). The data out of the serializer forms a serial bit stream which is coupled to the cathode ray tube to modulate the intensity of the beam in synchronism with the sweep to display the selected character data.
