A graphics processing unit or GPU is used to accelerate the building of images for output to display. The term GPU was first defined in 1999 by the manufacturer of the world’s first GPU, Nvidia. Most GPUs made since 1995 have supported hardware overlays and YUV color space. Today's modern GPU hardware is used for video decoding processes that include inverse quantization (IQ), motion compensation (mocomp), Intra-frame prediction, variable-length decoding (VLD), bitstream processing (CAVLC/CABAC), and more.AUTHOR
