Abstract
This paper proposes a unified HEVC $4{\times}4$ IDCT/IDST architecture for area reduction. In general, $4{\times}4$ IDCT and $4{\times}4$ IDST blocks are implemented separately, and they are connected with multiplexers. In the proposed arechitecture, these two blocks are unified, and internal hardware resources such as multipliers are shared. This reduces the chip area. The synthesized block in 0.18 um technology is 2,795 gates, and the gate count is reduced by 9.44% in comparison with conventional designs.
