Abstract
PURPOSE:To reduce the correction processing time without reading all series data on each occasion to obtain a syndrome by providing a syndrome register storing at least one syndrome in row/column directions and correcting the syndrome of the other series in correcting an error symbol. CONSTITUTION:A data from an input terminal 20 is sent to a C1 demodulator 11 via a switch 15, the error correction processing in the row (C1 series) direction and the result is stored in the C1 syndrome register 13. Then the data is fed to a C2 demodulator via a switch circuit 16 and the error correction processing in the column direction (C2 series) in implemented. In this case, the register 13 is updated by a C1 syndrome update circuit 21 in response to the symbol whose error is corrected. Thus, it is not required to read all the data of the series after the correction of error symbol and the correction processing time is reduced.
