    • A control device (211) inputs reliability information on the same data block a plurality of times into a reliability storage memory (202). A reliability generating device (201) generates anew reliability information by performing computation processing based on a stochastic computation by using reliability information generated in the previous cycle that has been saved in the reliability storage memory (202) and reliability information generated in the present cycle, and saves the reliability information generated anew in the reliability storage memory (202) when the decoding is performed by using reliability information on the data block same as that in the previous cycle. A column processing computation device (204) computes a column processing output value by using the reliability information generated anew and saved in the reliability storage memory (202) and a row processing output value.
    • 控制装置(211)将相同数据块上的可靠性信息多次输入到可靠性存储存储器(202)中。 可靠性生成装置(201)通过使用保存在可靠性存储器(202)中的上一个循环中生成的可靠性信息和在本周期中生成的可靠性信息,通过进行基于随机运算的计算处理,生成新的可靠性信息, 并且当通过使用与前一个周期相同的数据块的可靠性信息来执行解码时,将可靠性信息重新生成在可靠性存储存储器(202)中。 列处理计算装置(204)通过使用重新生成并保存在可靠性存储存储器(202)中的可靠性信息和行处理输出值来计算列处理输出值。
