Systems and apparatuses for performing CABAC parallel encoding and decoding

A system, comprising:

• a source of uncompressed video information;
• and
• a processor to encode the uncompressed video information via a parallel encoder, wherein the parallel encoder comprises:
• a binarizer module to create a plurality of bins for a syntax element for information of a video stream;
• a context selection module to receive the plurality of bins from the binarizer module and to generate, in parallel, an index value and a most probable symbol (MPS) value for encoding each of the plurality of bins;
• and
• an arithmetic coding module to receive the plurality of bins from the binarizer module and to encode, in parallel, the plurality of bins from the binarizer module, the arithmetic coding module to encode the plurality of bins from the binarizer module in parallel with the context selector processing the plurality of bins from the binarizer module, the arithmetic coding module to receive the index value and the MPS value from the context selection module to encode a first and a second bin of the plurality of bins in parallel based on a first probability value and a second probability value, respectively, wherein the first and second probability values are determined via the generated index value and MPS value.

A computer program product comprising a tangible computer readable storage medium having computer usable program code for encoding video information, wherein the storage medium does not comprise a transitory signal, the computer program product including:

• computer readable program code for selecting a plurality of bins for a syntax element of the video information;
• computer readable program code for selecting a probability symbol value and a probability index value based upon processing, in parallel, the plurality of bins;
• and
• computer readable program code for encoding the plurality of bins in parallel and encoding the plurality of bins in parallel with the processing, in parallel, the plurality of bins, wherein the encoding of the plurality of bins is via selection of a plurality of probability values corresponding to the plurality of bins, wherein further selection of each probability value is via the probability symbol value and the probability index value.
