Summary:This disclosure relates to a video output circuit for high resolution character generation in a digital display unit. This output circuitry includes both character generation circuits and logic circuits, the latter of which fills in information bit areas adjacent to character bit areas which form a diagonal so as thereby to round out the character being displayed. In addition, the circuitry is adapted to change the position of such characters on the display screen so as to provide superscripts and subscripts as well as provide characters which are higher and wider than the normal character display. In order to minimize time lags in the generation display of such characters, the output circuitry is provided with a series of registers so that the character generation can be received in a sequential or pipelined manner.
