In this paper, the hardware-oriented structure analysis and an efficient and flexible bitstream parser for MPEG-4 video are presented. The analysis of bitstream structure explores processing requirement and design constraint for bitstream-level processing. The proposed architecture is basically RAM-based that can be reconfigured for various applications. For high bitrate as about 40 Mbit/s, it needs only about 19 MIPS to parse the bitstream. The impact of the proposed architecture on MPEG-4 video is to enhance and extend the processing for bit domain translation and related real time applications.
