blit = B = blivet

blitter /blit'r/ n.

[common] A special-purpose chip or hardware system built to perform blit operations, esp. used for fast implementation of bit-mapped graphics. The Commodore Amiga and a few other micros have these, but since 1990 the trend has been away from them (however, see cycle of reincarnation). Syn. raster blaster.
