Abstract :
High Efficiency Video Coding (HEVC) is the currently developing video coding standard by the MPEG and ITU organizations. Unlike previous video codec standards, HEVC employs variable block size integer DCT/IDCT to conduct spatial redundancy compression. In this paper, a novel 2-D IDCT VLSI architecture for HEVC standard is presented. Using adaptive block size scheduling scheme, the proposed architecture supports variable block size IDCT from 4×4 to 32×32 pixels with low hardware overhead while keeping the highest performance. Using TSMC 65nm 1P9M technology, the synthesis result shows that the 2-D architecture achieves the maximum work frequency at 400MHz and the hardware cost is about 112.5K Gates. Experimental results show that the proposed architecture is able to deal with real-time adaptive HEVC IDCT of 4K×2K (4096×2048)@30fps video sequence at 179.4MHz. In consequence, it offers a cost-effective solution for the future UHD applications.
