INTERPRETIVE DISPLAY PROCESSOR

摘要

A display processor contains a random access memory which stores digital codes representative of text and display commands which define the addresses of strings of the text characters within the RAM and define the manner and position in which they are to be displayed on a cathode ray tube output device. A general purpose computer is used to load the RAM with text and display commands and to modify these in order to edit the display. A recirculating register capable of storing text characters for the generation of a single line of the CRT display is filled with portions of the text under control of the sequence of display commands. The contents of the buffer are generated on the CRT through use of a read only memory in dot matrix form.
