ABSTRACT:
A palette device controllable by a digital computer with a video memory having a bus for supplying multiple color codes for the palette device in each bus cycle. The palette device includes a multiple-bit input for entry of the color codes from the bus, and a look-up table memory for supplying color data words in response to the color codes from the input. Color code transfer circuitry is connected between the input and the look-up table memory to supply the look-up table memory from the input sequentially with color codes of selectable width packing the entire width of the bus. Improved palette devices, graphics computer systems, facsimile systems, printer systems and other systems and methods are also disclosed.
