[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.
cycle of reincarnation: [coined by Ivan Sutherland ca. 1970] n.
Term used to refer to a well-known effect whereby function in a
computing system family is migrated out to special-purpose
peripheral hardware for speed, then the peripheral evolves toward
more computing power as it does its job, then somebody notices that
it is inefficient to support two asymmetrical processors in the
architecture and folds the function back into the main CPU, at
which point the cycle begins again....
