Abstract
In this paper, we propose the VLSI design of Multi-Format Video Decoder (MFD) to support video codec standards such as MPEG-2, MPEG-4, H.264 and VC-1. The target of the proposed MFD is the Full HD (High Definition) video processing needed for the high-end D-TV SoC (System-on-Chip). The size of the design is reduced by sharing the common large-size resources such as the RISC processor and the on-chip memory among the different codecs. In addition, a detachable architecture is introduced in order to easily add or remove the codecs. The detachable architecture preserves the stability of the previously designed and verified codecs. The size of the design is about 2.4 M gates and the operating clock frequency is 225MHz in the Samsung 65nm process. The proposed MFD supports more than Full-HD (1080p@30fps) video decoding, and the largest number of video codec standards known so far.
