HARDWARE/FIRMWARE CRT DISPLAY LINK SYSTEM

摘要

A hardware/firmware control system for a video display system is disclosed wherein variable length rots of binary video information may be randomly stored in a display memory, and re-ordered for display on a CRT screen without requiring a reconstruction of the video information as stored in the display memory. Each row of video information in the display memory includes a firmware code which upon detection by hardware logic is used to address a first data character of a next row of video information to be read from the display memory. Both row insertions and deletions may be accommodated without requiring a memory rewrite of the video information.
