Abstract

PURPOSE:To exactly detect an error of a data, by comparing the contents of a data on a bus line with those of the previous data which has been outputted to this bus line. CONSTITUTION:A logical operation circuit 2 sends out a data onto a bus line 1 through a controlling circuit 3, and also supplies this data to a dissidence detecting circuit 4. When the circuit 3 has sent out a data onto the bus 1 by a control signal 3a, other data channel 6 also sends out a data onto the bus 1, and as a result, the data on the bus 1 interfere with each other and become other data. The circuit 4 compares the data of the circuit 2 and the data on the bus 1, corresponding to a bit, therefore, when dissidence of both the data has been detected, a signal 4a is outputted. By the signal 4a, an outputting circuit 5 outputs a signal 5a informing that an error has been generated in the data, in accordance with a control signal 5b.
