Abstract
Some of the circuits for executing processes on the physical layer are accommodated in a first chip that includes a link layer circuit. More specifically, an arbiter circuit composed only of a logic circuitry and having a relatively large circuit scale, and state machines, built in a control circuit, are accommodated in the first chip in the form of a control signal generation circuit. The other portions of the physical layer circuit remains in the second chip. A higher degree of integration of the first chip results in a higher degree of integration of many of the circuitry for executing processes on the physical layer.
