<P>PROBLEM TO BE SOLVED: To obtain a decoding device whose circuit scale is reduced. <P>SOLUTION: The decoding device for performing error correction processing on the basis of a code word comprising data, an error detection code and an error correction code with the maximum correction capability defined as a T-bit, together with an error correction processing part for performing error correction processing on the basis of a code word using a computing element which can respond up to a J (J is an integer of ≥1 and <T) bit error with at least a portion of processing on the basis of the code word, controls the error correction processing part so as to perform an arithmetic operation corresponding to a set error number expectation value with the error number expectation value defined as an initial value I (I is an integer of ≥1 and <T) when starting error correction processing, ends the processing when an error detection part does not detect an error in the data after error correction on the basis of an error detection code, and repeats an operation for the error correction processing part so as to increase the error number expectation value to perform an arithmetic operation until the error detection detects an error no more or until the error number expectation value is a T-bit when an error is detected in the data after error correction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
