ABSTRACT:
In a pixel based color display system, a pixel responsive control is provided for high speed loading of new colors in the random access memory of the system used as a look-up table. In the system, pixel words representing addresses in a random access memory in which colors to be displayed are stored are applied in sequence to the random access memory to cause the colors to be read out in sequence to generate red, green and blue video signals representing the colors read out from the random access memory. The pixel responsive control responds to a predetermined pixel word in the stream of pixel words applied to the address port of the random access memory to cause a new color to be stored in a selected storage location of the random access memory. The new color and the address in which the new color is to be stored is specified in the pixel words immediately following the predetermined pixel word.
