Abstract: Apparatus for serializing 2 parallel outputs of an all points addressable memory into successive data groups, each data group corresponding to a respective value for a pixel in an image wherein the bit-length of the pixel value is selectable, the apparatus comprising: a gate circuit having (i) 2 parallel input junctions connected to the outputs of the memory and (ii) 2 output junctions, wherein the gate circuit selectively converts each set of 2 parallel inputs at said input junctions into 2 successive data groups, each group having a bit-length of 2 bits, wherein each group is transmitted to 2 of the 2 output junctions; and a communication element for conveying to the gate circuit a signal which controls the bit-length 2 of data groups, wherein n is an integer 1
