Real-Time High Definition H.264 Video Decode Using the Xbox 360 GPU

摘要

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 (1920 1080) video. We report our experiences in developing a real-time, software-only high-definition video decoder for the Xbox 360.
