1. A method for error correction in a data processing circuit configured to carry out a syndrome calculation, comprising:
carrying out a syndrome calculation in a code domain of a second code, using the data processing circuit, and
carrying out an efficient error correction algorithm in a code domain of a first code, using the data processing circuit;
wherein the method comprises, between the syndrome calculation and carrying out the efficient error correction algorithm, transitioning between the code domains by means of at least one linear mapping.
