The Xbox 360 is powered by three dual pipeline 3.2 GHz IBM PowerPC processors and a 500 MHz ATI graphics
processing unit. The Graphics Processing Unit (GPU) is a special-purpose device, intended to create advanced visual
effects and to render realistic scenes for the latest Xbox 360 games. In this paper, we report work on using the GPU as a
parallel processing unit to accelerate the decoding of H.264/AVC high-definition (1920x1080) video. We report our
experiences in developing a real-time, software-only high-definition video decoder for the Xbox 360.
