blitter/blit'r/ (Or "{raster blaster}"). A special-purpose {integrated circuit} or hardware system built to perform {blit} (or "{bit bang}") operations, especially used for fast implementation of {bit-mapped} graphics. The {Commodore} {Amiga} and a few other {microcomputers} have these, but in 1991 the trend is away from them (however, see {cycle of reincarnation}). [{Jargon File}] (1996-04-30)
