Abstract

An interconnect interface is applied between sockets or between dies. The interconnect interface includes a first transmitter (TX), a first receiver (RX), and an electrical physical layer (EPHY) coupled between the first TX and the first RX. The data provided by a first device is transmitted from the first TX to the EPHY and then received by the first RX to be retrieved by a second device. The first TX includes an arbiter for arbitrating between a plurality of channels of the first device to obtain data from the first device. The first TX includes a packet generator, which packs the data obtained from the first device into a packet to be transmitted through the EPHY. The first TX further includes a first buffer that backs up the data obtained from the first device for retransmission.
