VLSI ARCHITECTURES FOR VIDEO COMPRESSION

摘要

This paper gives an overview on alternative approaches for the implementation of recent hybrid coding schemes. An efficiency measure is introduced and applied for the comparison of video signal processors, proposed in the literature. Concerning recent hybrid coding schemes, the comparison shows that adapted architectures achieve an efficiency gain by a factor of 6 to 7 compared to flexible architectures, applicable for a wider range of application fields. It is expounded that this efficiency might decrease for future video compression schemes, due to data dependent computational requirements of the applied algorithms.
