Abstract:
A decoding device comprises two check node processing devices of feedback shift register type, each of which node processing includes a plurality of registers and a plurality of comparator circuits. A multiplexer and a demultiplexer switch between the two check node processing devices, and a memory holds the two sorts of data. The comparator circuits are interposed between registers of the check node processing device.
