Bitblt (pronounced “bit blit”) stands for “bit-block transfer.”. The BLT originated as an assembly language instruction that did memory block transfers on the DEC PDP-10.

WebThe Atari ST Bit-Block Transfer Processor (BLiTTER), in high level terms, is a chip dedicated to moving data around in memory independant of the main CPU, typically used to perform graphical operations smoothly (such as scrolling) while leaving the CPU to perform other tasks.. In low level terms, it is a hardware implementation of the bit-block transfer … Bit blit (also written BITBLT, BIT BLT, BitBLT, Bit BLT, Bit Blt etc., which stands for bit block transfer) is a data operation commonly used in computer graphics in which several bitmaps are combined into one using a boolean function. The operation involves at least two bitmaps: a "source" (or "foreground") and a … See more The name derives from the BitBLT routine for the Xerox Alto computer, standing for bit-boundary block transfer. Dan Ingalls, Larry Tesler, Bob Sproull, and Diana Merry programmed this operation at Xerox PARC in November 1975 … See more • Alpha compositing • Mask (computing), used here as a stencil • Blitter See more • Performance demonstration coded in Flash/AS3 • Xerox Inter-Office Memorandum 19 November 1975 See more A classic use for blitting is to render transparent sprites onto a background. In this example a background image, a sprite, and a 1-bit … See more Blitting is similar to hardware-sprite drawing, in that both systems reproduce a pattern, typically a square area, at different locations on the screen. Hardware sprites have the advantage of being stored in separate memory, and therefore don't disturb the main … See more maximus to himself poem
