ABSTRACT:
A character generator for a raster scanned display includes a virtual memory, a character memory, and character memory addressing circuitry. Character identifying codes are received by the virtual memory which produces the addresses in the character memory for the data for the first scanned line of each character. The character data for each scanned data line of a character contains sequential words containing N bits of video data to be displayed and two link bits. The link bits apprise the character memory addressing circuitry if subsequent words for that character appear on that scanned data line and if additional data lines for that character will have to be read on subsequent scans of the raster display frame.
