<p>An error correcting system for performing error correction over error codewords sequentially received in a codeword string on a pipeline processing basis. The system comprises a processing block (11) for generating a syndrome data on the basis of parity symbols of each of the codewords, a processing block (12) for performing logical processing operation to derive error locations and error values on the basis of the syndrome data, and a processing block (13) for performing correcting operation over the codeword delayed based on the error locations and values. These three processing blocks start their processing operation when receiving individual control signals based on reset signals indicative of leading heads of the respective codewords in the string and delayed by mutually different delay times. With regard to incomplete ones of the codewords shorter than a right codeword length, the logical processing operation for the error location and error evaluation as well as the error correcting operation is inhibited. <IMAGE></p>
