Abstract
A method and processor for providing context-based adaptive binary arithmetic CABAC coding. Binarization is performed on one or more syntax elements to obtain a binary sequence. Data bits of the said binary sequence are provided to an arithmetic encoding unit in bulk. Binarization is performed on one or more syntax elements to generate exp Golomb code by converting mapped syntax-element values to corresponding floating point type values. Re-normalization of CABAC encoding is performed by restructuring the re-normalization into two processing units including an arithmetic encoding unit and a bit writing unit. The bit writing unit is configured to format signal bits into a multiple-bit sequence, and write multiple bits simultaneously during an execution of a bit writing loop.
