The Atari ST Bit-Block Transfer Processor (BLiTTER) is a hardware implementation of the bit-block transfer (BitBlt) algorithm. BitBlt can be simply described as a procedure that moves bit-aligned data from a source location to a destination location through a given logic operation. The BitBlt primitive can be used to perform such operations as:

* Area seed filling
* Rotation by recursive subdivision
* Slice and smear magnification
* Brush line drawing using Bresenham DDA
* Text transformations (eg. bold, italic, outline)
* Text scrolling
* Window updating
* Pattern filling

The blitter chip first became available in the [[Mega ST]] range, followed by the [[STE]] and [[Mega STE]]. It was also available as an upgrade for the standard [[ST]] range but not the [[TT]].
