  • 在本篇論文中,我們針對先進視訊影像壓縮技術 (H.264 Advanced Video Coding) 提出一個有效率的變動長度解碼反離散餘弦轉換和反量化架構設計。我們的設計支援省略模式功能在輸入區塊(Block 16x16 8x8 4x4)經由運算後的結果全為零值時,略過核心運算,直接輸出零值,由此減少運算的時間以及消耗的功率。而相較於傳統的設計,我們加入了變動長度解碼的功能,因此減少了記憶體存取需求。目前,我們已經將提出的架構設計整合入實驗室發展的H.264影像解碼器中,同時也在FPGA發展板上做驗證和實驗。


    We propose an efficient hardware architecture for Inverse Quantization/Inverse Discrete Cosine Transform (IQ/IDCT) in H.264/AVC. Our design supports bypass mode for skipping blocks with zero transformed coefficients. We integrate Run Level Decoding (RLD) into our IQ/IDCT to reduce memory bandwidth. We have integrated the hardware IQ/IDCT into an H.264/AVC main profile decoder in FPGA prototype.
