![]() Because its entropy encoding block is also a separately accessible Video Codec Engine, it can be operated in two modes: full-fixed mode and hybrid mode. It is capable of delivering 1080p at 60 frames/sec. As the template compression methods shows, lossy video compression algorithms involve the steps: motion estimation (ME), discrete cosine transform (DCT), and entropy encoding (EC).ĪMD Video Code Engine (VCE) is a full hardware implementation of the video codec H.264/MPEG-4 AVC. ![]() The handling of video data involves computation of data compression algorithms and possibly of video processing algorithms. Using AMD's Accelerated Parallel Programming SDK and OpenCL developers can create hybrid encoders that pair custom motion estimation, inverse discrete cosine transform and motion compensation with the hardware entropy encoding to achieve faster than real-time encoding. In "hybrid mode" most of the computation is done by the 3D engine of the GPU. The entropy encoding block of the VCE ASIC is also separately accessible, enabling "hybrid mode". Full-fixed mode can be accessed through the OpenMAX IL API. Overview In "full-fixed mode" the entire computation is done by the fixed-function VCE unit. VCE occupies a considerable amount of the die surface at the time of its introduction and is not to be confused with AMD's Unified Video Decoder (UVD).Īs of AMD Raven Ridge (released January 2018), UVD and VCE were succeeded by Video Core Next (VCN). ![]() VCE was introduced with the Radeon HD 7000 Series on 22 December 2011. Since 2012 it was integrated into all of their GPUs and APUs except Oland. Video Code Engine ( VCE, was earlier referred to as Video Coding Engine, Video Compression Engine or Video Codec Engine in official AMD documentation) is AMD's video encoding application-specific integrated circuit implementing the video codec H.264/MPEG-4 AVC. ![]() AMD hardware accelerator for encoding MP4 H.264 videos, built into AMD GPU's ![]()
