Architecture Design of the Double-Mode Binarization for High-Profile H.264/AVC Compression

The efficiency of hardware video encoders depends on all modules embedded in the processing path. This paper presents the architecture of the H.264/AVC binarization unit, which is a part of the last stage of the video coder. The module supports CABAC and CAVLC modes and conforms to H.264/AVC High Profile. The architecture saves a considerable amount of hardware resources since two coding modes share the same logic and storage elements. For both modes, the architecture achieves the similar throughput able to support HDTV.
