PROBLEM TO BE SOLVED: To overcome such a problem that the power consumption of the wire increases owing to an increase in wire capacity associated with the increase in wire density, when wires increase in density by being made minute. SOLUTION: A device is equipped with an encoding device having an output-side delay means which is provided for at least one of signal lines constituting a bus and inputs a digital signal of bits corresponding to the signal line and delays the signal in stages, and output-side arithmetic means which operates logical exclusive OR of the digital signal of bits inputted to the output-side delay means and delay signals of the respective stages obtained by delaying the digital signal by the output-stage delay means, and a decoding device having an input-side delay means which is provided for a signal line behind the encoding device and delays an inputted digital signal in stages and an input-side arithmetic means which operates logical exclusive Ors of the digital signal from the signal line and delay signals of the respective stages obtained by delaying the digital signal by the input-side delay means and inputs the arithmetic result to the input-side delay means.
