A computer implemented method of controlling the decoding of codewords received by a linear block code pipelined decoder from an input buffer, the pipelined decoder comprising at least two decoding stages. The method comprises iteratively: loading the decoding stages of the pipelined decoder, executing a decoding step, determining the number of residual errors in the codewords and outputting error free codewords. The method allows the different decoding stages to be loaded with any codeword coming from the buffer or from any decoding stage of the decoder. Accordingly, the occupation rate of the pipeline is improved.
