Abstract:
1. A data transmission device that transmits transmission data converted into encoded data, using n-bit (n being k×m, k and m being natural numbers each equal to or greater than 1) signal lines, the data transmission device comprising: an arithmetic operation unit that generates difference data that includes a positive value and a negative value and outputs sequentially the positive value and the negative value, the difference data representing a difference between first data for m bits of the transmission data and second data for m bits of a previous set of the transmission data; and an encoding unit that encodes the difference data and generates m-bit encoded data, the encoding unit performing encoding to associate the encoded data with the difference data in such a manner that a number of bit inversions with respect to encoded data associated with the difference data “0” becomes smaller as an absolute value of the difference data becomes smaller.
