Abstract
A display system is described which includes storage for receiving a compressed pixel image manifesting at least a pair of encoded colors and a bit MASK that defines which pixels of a pixel subset of the pixel image receive one of the colors. The system comprises a plurality of memory modules. The pixels in the subset are interleaved in the memory modules. A generator is provided for applying signals to cause data to be written into each of modules in parallel. Register means are provided for applying data manifesting the encoded colors to the modules. Control apparatus is responsive to the MASK bits for controlling the generator to write the encoded color data, in parallel and in a single memory cycle, into all pixel positions of the subset that are designated for the color(s) by MASK bit position values.
