摘要： A frame buffer for accelerating the display of graphics data on an output display device which frame buffer includes a pair of color value registers each of which may be loaded with color values prior to writing to the frame buffer. Selection means are provided for selecting pixel data from the bus, from a first of the color value registers, from the second of the color value registers, or from both color value registers simultaneously. When data is written to the frame buffer from color value registers it may be written to a number of pixel positions simultaneously.

摘要： A method and apparatus for performing anti-aliasing of rendered lines, text and images displayed by a workstation on a video display. The anti-aliasing is performed by logically dividing each addressable frame buffer pixel into sixteen sub-pixels and generating a gray scale value for the displayed pixel that is a function of the number of sub-pixels crossed by a portion of a rendered image. The invented circuitry is part of the circuitry used for combining source and destination data which forms the displayed image namely, an anti-aliasing mask and filter, adder/subtractor logic, saturation logic and anti-aliasing logic.

摘要： An apparatus and method for using a test window to improve the efficiency of clipping and inter-coordinate images which are to be displayed by a graphic display subsystem. A test window is defined which surrounds a window (the clip window) within which it is desired to render graphical images. Objects are then tested to see if their vertices are outside the test window. The utilization of this window allows for a performance optimization to be made between processing of a clipped object by a hardware based graphics subsystem which incorporates the present invention or by graphic software executed by a general purpose CPU which also interfaces to the graphics display. By properly defining the test window size relative to the clip window, objects which fall totally within the test window, will be rendered faster by the graphics subsystem rather than deferring the object to graphics software. Objects with vertices that fall outside the test window would be deferred to graphics software to render.

摘要： An apparatus and method for processing graphical information in a manner such that 1) accesses to a frame buffer in which the graphical information is to be stored result in a minimum of page crossings in the frame buffer; and 2) time spent processing graphical information outside a predetermined clip window is minimized. These two goals are sometimes conflicting and the present invention determines how the graphical information should be processed so that frame buffer accesses are always performed with the least overhead. For a given object which is to be displayed within a defined window, by determining the portions of the object which are inside the window and the portions which are outside the window, it frequently is possible to determine whether the object should be drawn from top to bottom, bottom to top, left to right or right to left so as to minimize page crossings and minimize the time spent processing portions of the object outside a predetermined clip window.
