ABSTRACT:
The objective of the invention is to offer a Reed-Solomon decoding device in which it is possible to perform decoding calculations at high speed without greatly increasing the circuit scale. The present invention has a decoding calculation input parameter calculator 309 that generates decoding calculation input parameters including syndrome and fail data from a data string, a decoding calculator processing section 304 that performs decoding calculations using the decoding calculation input parameters based on the command codes showing the prescribed decoding calculation operation, and generates decoding calculation output parameters including error value data and error position data, a correction operation implementer 312 that performs correction operations by using the above-mentioned decoding calculation output parameters, and a register B 313 that selectively stores the decoding calculation input parameters output to the decoding calculation processing section 304, and the decoding calculation output parameters that are output to the corrections operation implementer 312.
