    • A decoding device has a buffer configured in memory to store N code streams and N decoders connected in series. Each of N decoders decodes a corresponding code steam and sequentially generates partial symbols of M bit width each unit cycle. Among the N decoders, i (i>=2) stage decoders stores multiple probabilistic models in the memory. In each unit cycle, the decoder receives an input of i−1 partial symbols which contains partial symbols generated by the i−1 stage decoder in the former unit cycle, selects one probabilistic model among the multiple probabilistic models based on i−1 partial symbols which are entered previously, generates one partial symbol using previously selected probabilistic models, and outputs the previously generated one partial symbol along with previously entered i−1 partial symbols.
    • 解码装置具有配置在存储器中的缓冲器,用于存储串联连接的N个码流和N个解码器。 N个解码器中的每一个解码对应的代码蒸汽,并且顺序地产生每单位周期的M位宽度的部分符号。 在N个解码器中,i(i> = 2)级解码器在存储器中存储多个概率模型。 在每个单元周期中,解码器接收包含由i-1级解码器在前一单位周期中产生的部分符号的i-1部分符号的输入,基于i-1个部分符号在多个概率模型中选择一个概率模型 它们先前输入,使用先前选择的概率模型生成一个部分符号,并输出先前生成的一个部分符号以及先前输入的i-1部分符号。
