VLSI architecture for MPEG-4 core profile video codec

摘要

In this paper a VLSI architecture of the MPEG-4 Core Profile video codec is described. Although a great number of authors have reported on the MPEG-4 Simple Profile codec, there rarely exists the one of such high performance as to be capable of the shape codec. Thus, first a performance verification model is formed with the use of parameters of bath widths and calculation performances of functional modules, each constructed as a specific processing unit of the total codec, and then these parameters are attempted to be optimized to make the MPEG-4 Core Profile codec attain the maximum possible performance. The shape coder core, motion estimation core, and motion compensation core architectures are also described dedicatedly for the object base coding.
