Reception circuit, information processing device, and buffer control method

摘要

A reception circuit (301) that receives data in serial communications through a plurality of lanes includes a plurality of buffers (314) provided for each of the plurality of lanes, each of which stores data received through a corresponding lane. A multilane control circuit (303) detects the skew between the lanes, and outputs an adjustment instruction for adjusting a read address of a buffer and deskew information indicating that a skew adjustment between the lanes is to be performed based on the detected skew. A plurality of address control circuits (315) are provided for each of the plurality of lanes, each of which transmits the adjustment instruction to a corresponding buffer when receiving the deskew information, wherein the buffer (314) that has received the adjustment instruction adjusts its read address.
