Abstract
The present terminal independent color memory for a digital image display system provides for inter-system compatability, color display systems generally having varying modes of access to color memories, varying color memory capacities, and features such as blinking implemented in varying ways. The data processor (1) of the present system may access color memory (6a) of video controller (6) or color values stored in permanent memory (9) or random access memory (10), responsive to the same command language. The present data processor (1) is also capable of entering color data values comprising color hues and gray levels into color memory for use in a terminal independent manner. Multiple process chained blinking from a particular color to a particular color is also provided by the present processor, the several processes in time-delayed relationship to one another.
