Abstract
A coding-decoding device and a coding-decoding method that take less time for coding and decoding are provided while using less number of logic gates. A memory devicesubstantially stores b pieces of conversion logic equations produced with a conversion logic equation producing device. An operation devicehas a programmable hardware logic circuit to constitute logics sequentially according to plural execution unit logic equations obtained by dividing b pieces of conversion logic equations stored in the memory deviceinto execution units for respective execution unit logic equations using the hardware logic circuit. Besides, the operation devicesequentially divides and calculates the second sentences from the first sentences according to the constituted logics. An output devicecollects and outputs the second sentences calculated with the operation device
