Data processing system and apparatus for color graphics display

摘要: A system and apparatus for managing the picture memory of a digital color graphics imaging system, thereby enabling images on display monitor to be changed efficiently at high rates, more specifically control which comprises video controller having an internal system. The operates under direction host computer generate synchronized data signals input cathode ray tube or other suitable graphical device. is effective randomly address its speed serially read, but not write, stored in TV rates displaying monitor. particular embodiment disclosed herein has universal organization may adapted use various systems. operated by software capable automatic stepping X Y directions provide transfer into using first word length out from second longer length, including specific registers addressing controller's those locations specified are reached incrementing decrementing one step and/or loading new absolute address, being determining changing values each presentation location based upon previous value that same combined with computer.
