Abstract
An apparatus includes: a physical-layer device that distributes data to first lanes and performs data transfer to/from an external device by second lanes each of which has a number of the first lanes; and a transfer circuit that transfers data output by a central-processing unit performing arithmetic-processing to the physical-layer device and transfers the data received from the physical-layer device and received by the central-processing unit, the transfer circuit that comprises an information-acquisition unit that receives one of detection information of the first lanes which indicates that the physical-layer device has received data from the external device and error information of the first lanes which indicates that the data transferred to the physical-layer device from the external device has an error, from the physical-layer device, and a selection unit configured to specify the second lane to be degenerated based on one of the error information and the detection information.
