ABSTRACT:
A computer instruction is described which expands compressed font information to provide an expanded format suitable for driving a display for example. The expansion is carried out by identifying a bit string having at least one bit sequence, selecting each bit of the bit sequence and replicating each selected bit at a plurality of adjacent locations. This is carried out in a register store having a predetermined bit capacity addressable by a single address. The instruction is particularly useful for generating background or foreground font information for driving a display.
