In this paper, we presented an SoC based HW/SW co-design architecture for multi-standard audio decoding. It is developed to support the audio standards of AAC LC profile, Dolby AC3, Ogg Vorbis, MPEG-1 Layer 3 (MP3) and Windows Media Audio (WMA). A VLSI reconfigurable filterbank based on CORDIC algorithm is developed to accelerate the multi-standard decoding process. We designed and implemented an...
H.264 and AVS are the two latest video coding standards. Since the similarity between their structures, it is feasible to develop a dual-mode VLSI decoder for supporting both standards, with substantially less cost than the solution with two individual decoders. In this paper, we propose a dual-standard VLSI architecture for MC interpolation, which is the most calculation intensive module of the dual-mode...
