摘要
Methods and apparatus that reduce the error rate of a Serial-De-Serial (SerDes) backplane connection are shown. The apparatus may include a receiver verifying a received block of data at the PHY layer. When the received block of data is received correctly, that block can be acknowledged by the receiver to the transmitter, which is also located at the PHY later. Upon detection of an error in a block of data, the receiver may send a negative acknowledge along with the block number, or some other suitable block identifier, of the faulty block to the transmitter. The transmitter may buffer blocks of data, and remove each block from the buffer upon receiving an acknowledgement. Use of the retransmission protocol may be triggered by speed of the connection, the bandwidth of the connection, the detection of too many errors in the connection or any suitable combination of these, or other, parameters.
