PARALLEL ENCODING OF BYPASS BINARY SYMBOLS IN CABAC ENCODER

A video encoder may include a context-adaptive binary arithmetic coding (CABAC) encode component that converts each syntax element of a representation of a block of pixels to binary code, serializes it, and codes it mathematically with its probability model, after which the resulting bit stream is output. When the probability of a bin being coded with one of two possible symbols is one-half, the bin may be coded using bypass bin coding mode rather than a more compute-intensive regular bin coding mode. The CABAC encoder may code multiple consecutive bypass bins in a series of cascaded processing units during a single processing cycle (e.g., a regular bin coding cycle). Intermediate outputs of each processing unit may be coupled to inputs of the next processing unit. A resolver unit may accept intermediate outputs of the processing units and generate final output bits for the bypass bins.
