ABSTRACT:
An error correcting apparatus including a syndrome calculator for calculating syndromes from input data added with an error correction code, a data memory which is connected in parallel with the syndrome calculator for storing the input data, a syndrome memory to store syndromes calculated by the syndrome calculator, and an error correction processor for executing error correction of the data in the data memory by using the syndromes stored in the syndrome memory. The error correction code is provided in both first and second directions when data is two-dimensionally arranged, and the error correction processor obtains values in which the result of an arithmetic operation for error correction in at least one of the first and second directions is added to syndromes in the other direction. An error position within the input data is detected and corrected again on the basis of the values.
