ABSTRACT:
Binary arithmetic decoding methods and apparatus are provided. A first decoded bit and a first set of decoding parameters are generated using a previously generated set of decoding parameters. A second decoded bit and a second set of decoding parameters are generated using the first set of decoding parameters. If the first decoded bit is a last bit of a syntax element, the second set of decoding parameters is disregarded in generating subsequent decoded bits. The generation of the first and second decoded bits and determination of whether the first decoded bit is a last bit of a syntax element, e.g., a de-binarizing operation, may be pipelined such that the determination of whether the first decoded bit is a last bit of a syntax element occurs concurrent with and/or after generation of the second decoded bit and the second set of decoding parameters.
