Abstract
In a bus circuit which includes a plurality of signal lines, insertion pattern &agr;, which provides repeaters in only an odd numbered series of signal lines, and insertion pattern &bgr;, of which the segment length is equal to that of pattern &agr; and which provides repeaters to only an even numbered series of signal lines, are arranged in an alternating manner in accordance with the length of the signal lines. As a result, the segments during which data signals on the neighboring signal lines run together in opposite phases become half the entire length of the signal lines. Therefore, this bus circuit can prevent the operational speed from becoming slowed.
