ABSTRACT:
A microprocessor based data processing system including a microprocessor, a memory unit, and a display unit is provided with a programmable graphics generator that transfers graphics information from the memory unit to the display unit in response to and control of a set of display instructions also stored in the memory unit. The graphics generator includes a first addressing unit for sequentially accessing the display instructions from the memory unit; a control unit for receiving, storing and decoding such instruction and for issuing supervisory and control signals in response to the binary state of each instruction; a second addressing unit for accessing graphics information from the memory unit in response to the supervisory signals from the control unit; and a third addressing unit for accessing movable object graphics stored in the memory unit.
