Abstract
Graphics commands for a display are listed and divided into sublists corresponding to separate strips or bands of the display, and these sublists drive the display memory consecutively and substantially concurrently with the processing of additional sublists. Graphics commands relating to graphics extending between bands are transferred to successive sublists during processing to provide their display in successive bands. A pair of band size bit map memories are alternately loaded with band information and read out.
