1. A context-based adaptive binary arithmetic coding (CABAC) decoding device, comprising: a context memory address calculator arranged to calculate an address identifying a memory location in a context model memory for storage of a context model in a next cycle; a mixed context memory to store the context model of the context memory address calculator; a two-bin context adaptive binary arithmetic decoder arranged to output a plurality of parameters for updating a range and an offset of the context model based on the context model of the mixed context memory, and to determine a plurality of bins; and a binary syntax element comparator arranged to determine whether a current binary sequence corresponds to a value of syntax elements, based on the bins so as to select a correct memory address.
