Patent ID: 8823696

Claim:
An information processing apparatus comprising: a first module including: a signal addition unit to generate an addition signal by adding a data signal to a clock, wherein the addition signal comprises a first component of the data signal having a first phase; a signal subtraction unit to generate a subtraction signal by subtracting the data signal from the clock, wherein the subtraction signal comprises a second component of the data signal having a second phase that is opposite to the first phase; a first signal transmission unit to transmit the addition signal through a first transmission line; and a second signal transmission unit to transmit the subtraction signal through a second transmission line; and a second module including: a data component extraction unit to extract a component of the data signal by subtracting the subtraction signal generated by subtracting the data signal from the clock and received through the second transmission line from the addition signal generated by adding the data signal to the clock and received through the first transmission line, and a clock component extraction unit to extract a component of the clock by adding the subtraction signal generated by subtracting the data signal from the clock and received through the second transmission line to the addition signal generated by adding the data signal to the clock and received through the first transmission line.
