An RVC dataflow description of the AVC Constrained Baseline Profile decoder

Video codec applications become more and more complex to design. To ease the description of such applications, MPEG creates a Framework called Reconfigurable Video Coding (RVC). All existing codecs in MPEG have a similar structure, they are based on a hybrid decoding structure and some of their part can be reused on other design. In RVC, the dataflow is expressed using a network of components also called Functional Units (FUs) interconnected by FIFOs. An FU, programmed in CAL Language, includes the processing and the internal states. This paper puts the focus on a parallel dataflow description of the most complex MPEG RVC decoder available called MPEG4-AVC Constrained Baseline Profile (CBP) decoder.
