摘要：An error correcting system for performing error correction over error

codewords sequentially received in a codeword string on a pipeline processing basis. Thesystem comprises a processing block (11) for generating a syndrome data on the basis ofparity 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 thesyndrome data, and a processing block (13) for performing correcting operation over thecodeword delayed based on the error locations and values. These three processingblocks start their processing operation when receiving individual control signals based onreset signals indicative of leading heads of the respective codewords in the string anddelayed by mutually different delay times. With regard to incomplete ones of thecodewords shorter than a right codeword length, the logical processing operation forthe error location and error evaluation as well as the error correcting operation isinhibited.
