An H.264/AVC encoder LSI (named “SARA/E”) that supports High422 profile, as well as 422 profile of MPEG-2, has been developed for HDTV broadcasting infrastructures. It contains three motion estimation and compensation (ME/MC) engines with search ranges of −217.75 to +199.75 (H) / −109.75 to +145.75 (V), which can utilize almost all H.264/AVC ME/MC tools, multiple reference frame, variable block size, 0.25-pel prediction, macroblock adaptive field/frame prediction (MBAFF), temporal/spatial direct mode, and weighted prediction. Our evaluations show that it can encode fast moving scenes with 1.2 dB to 1.7 dB higher than the JM. It was successfully fabricated in a 90 nm technology. It integrates 140 million transisters. |
