Title:
APPARATUS AND METHOD FOR GENERATING GRAPHIC INFORMATION
Document Type and Number:
Japanese Patent JPS59188774
Kind Code:
A
Abstract:
A microprocessor based data processing system including a microprocessor (40), a memory unit (42), and a display unit (22) is provided with a programmable graphics generator (44) that transfers graphics information from the memory unit (42) to the display unit (22) in response to and under the control of a set of display instructions also stored in the memory unit (42). The graphics generator (44) includes a first addressing unit (82) for sequentially accessing the display instructions from the memory unit (42); a control unit (88, 90) 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 (84) for accessing graphics information from the memory unit (42) in response to the supervisory signals from the control unit (88, 90); and a third addressing unit (86) for accessing movable object graphics stored in the memory unit (42).
