1. A display processor for conditioning pixel data for use by a utilization means such as a kinescope, said processor comprising: a first color map memory addressable by a first read address of p bits during its reading, p being a positive integer; a first pre-address register for temporarily storing a p-bit first pre-address; means for generating from said p-bit first pre-address said first read address; a second color map memory addressable by a second read address of q bits during its reading, q being a positive integer; a second pre-address register for temporarily storing a q-bit second address; means for generating from said q-bit second pre-address said second read address; a pixel input latch having a minimum width of (p+q) bits into which the data for respective pixels are serially loaded; means for selecting from the contents of said pixel input latch a first number of bits from adjacent bit places, said first number being no larger than p; means for applying the first number of bits in justified format to said first pre-address register as at least a portion of said first pre-address and applying ZEROs as any remaining portion of said first pre-address, to be temporarily stored in said first pre-address register; means for programmably selecting from the contents of said pixel input latch second number of bits from adjacent bit places, said second number being no larger than q; said means for programmably selecting a second number of bits being of a type in which there is a choice of which bit places are to be included in said second number that is independent of which bit places are included in said first number; means for applying the second number of bits in justified format to said second pre-address register as at least portion of said second pre-address and applying ZEROs as any remaining portion of said second pre-address, to be temporarily stored in said second pre-address register; and means coupled to said first and second color maps memories for applying data read from said color map memories to said utilization means.
