ABSTRACT:
Apparatus for addressing a character memory of a data display system in which displayed data is composed of discrete characters the shapes of which are determined by selected dots of a dot matrix. When character information conforms to different character modes of the form m.times.n.times.b, where m.times.n is a bit matrix format which is repeated b times to provide b-bits per displayed character dot, the stored character information includes mode bits which identify the mode. These mode bits are read out by logic control and addressing means by a first address and are used to determine a second address which varies according to the size of the mode and how many bit patterns it contains. The two addresses select all of the dot information required for the display of characters in real time.
