CONTEXT-BASED ADAPTIVE ARITHMETIC DECODING SYSTEM AND APPARATUS

摘要

The present invention discloses a context-based adaptive arithmetic decoding system and an apparatus thereof. The system includes a control unit, a decoding unit and a interface unit. The control unit is used for filling the code stream data in the decoding unit, and for configuring and controlling the decoding unit through the interface unit. The decoding unit is used for decoding all the expression elements from the code stream data in blocking layer, and regrouping the expression elements to transmit them to the control unit. The interface is used for transporting the interactive information between the decoding unit and the control unit. In the present invention, the realization for the CABAC decoded expression elements is performed by hardware manners as a whole, so the decoding efficiency is increased highly, and the requirements for the video processing speed and the data processing abilities in real-time and high-definition applying scenes can be achieved.
