Abstract

PURPOSE: To omit the decoder and to simplify the operation of the error detection circuit by constitute the error detection circuit using the block code with the encoder and the comparator.
CONSTITUTION: Input signal 6 of input/output control unit 4 is supplied to data buffer 8 as well as to encoder 11a. The output of buffer 8 is transferred to input/ output device 5 and also supplied to encoder 11b. Output signal 16 or 11a is compared (18) with output signal 17 of 11b when the transfer of the data block is over. If a coincidence is obtained, no error occurrence is dectected. In the sase of disagreement error occurrence is detected. This error detection system does not need the decoder, so the transfer of the error check code grown at the encoder to the decoder becomes unnecessary. Thus, the action of the circuit can be simplified
