Intra mode prediction is extended in high‐efficiency video coding (HEVC) for a higher coding efficiency than that specified in the previous video coding standards such as H.264/AVC. Improved coding was achieved mainly due to the increased block partition possibilities and types of modes at the expense of an increased computational complexity. Efficient 4 × 4 intra prediction logic combined with transform logic for HEVC is presented. The proposed design enables 108 frames/s intra prediction for full HD video with reasonable logic size.
