Parallel encoding of bypass binary symbols in cabac encoder

A method, comprising:

• receiving a plurality of binarized syntax element bits that represent pixels of a video frame;
• determining that a sequence of two or more consecutive binarized syntax element bits are to be coded by a context-adaptive binary arithmetic coding component in a bypass bin coding mode rather than in a regular bin coding mode;
• and
• in response to said determining, coding the sequence of two or more consecutive binarized syntax element bits during a single processing cycle of the context-adaptive binary arithmetic coding component;
• wherein the single processing cycle of the context-adaptive binary arithmetic coding component is of a duration insufficient for coding more than a single binarized syntax element bit in the regular bin coding mode.

A device, comprising:

• a memory;
• and
• an apparatus configured to process video frames and to store the processed video frames as frame data to the memory, the apparatus comprising a block processing pipeline that implements a plurality of stages each comprising one or more pipeline units, each pipeline unit configured to perform one or more operations on a block of pixels from a frame passing through the pipeline;
• wherein one or more of the pipeline units in the block processing pipeline are collectively configured to:
• receive a plurality of binarized syntax element bits that represent a portion of a block of pixels;
• determine, for each of the plurality of binarized syntax element bits, whether to code the syntax element bit in a regular bin coding mode of a context-adaptive binary arithmetic coding process or in a bypass bin coding mode of the context-adaptive binary arithmetic coding process, wherein only a single binarized syntax element bit can be coded in the regular bin coding mode during each context-adaptive binary arithmetic coding process cycle;
• and
• in response to receiving a sequence of two or more consecutive binarized syntax element bits for which it is determined that the binarized syntax element bits are to be coded in the bypass bin coding mode, code the sequence of two or more consecutive binarized syntax element bits during a single context-adaptive binary arithmetic coding process cycle.
