Abstract

PURPOSE:To attain error correction device with small circuit scale by providing a delay means retarding an input signal, a bit inverting means inverted by an error correction signal and a non-null detection means giving an error detection signal when the sign of residual is not zero so as to reduce the capacity of a ROM used for the converter. CONSTITUTION:The code conversion means 4 converting a 1st residual code obtained by the 1st division means 1 and outputting a check code, a coincidence detection means 5 outputting an error correction signal through the comparision of the residual code of the 2nd, 3rd... obtained by the 2nd, 3rd... division means 2, 3,... with a check code, a delay means 7 retarding the input signal by a prescribed clock ulse number, and the non-null detection means 9 outputting an error detection signal when at least one of the residual codes of the 1st, 2nd-Mth is not zero are provided. The coincidence detector 5 compares the residual code with the output of the code converter to generate an error correction signal thereby reducing the capacity of the ROM used for the code converter and reducing the circuit scale of the error corrector.
