  • Graphics display system and method including associative addressing
    Patent number: 4496944
    Abstract: A graphics display system is disclosed including a memory circuit for storing vector data representing a graphics image, a raster memory circuit for rasterizing the vector data into a second memory for storage, and a processor for controlling the operation of the vector memory and raster memory circuits. The raster data can be displayed on a suitable cathode ray tube monitor, thereby displaying the graphics image on the monitor.
    Type: Grant
    Filed: September 13, 1982
    Date of Patent: January 29, 1985
    Assignee: Calma Company
    Inventors: Arthur J. Collmeyer, Jeffrey H. Hoel, Paul F. King, Donald O. Stanley, Roger Sturgeon
