  • Patent number: 10333565
    Abstract: A transmitter for a high speed serial communications link, a serial communications link, and a receiver for a high speed serial communications link are disclosed herein. In one embodiment, the transmitter includes: (1) a communications interface connected to a transmission medium having multiple lanes, and (2) a safe mode circuit coupled to the communications interface and configured to send data over the transmission medium in a safe mode, wherein in the safe mode at least one of the lanes is dedicated to transmitting a link detect signal for link detection.
    Type: Grant

  • Patent number: 10200154
    Abstract: A receiver, transmitter and method for early packet header verification are provided. In one embodiment, the method includes: (1) receiving a payload flit of a preceding packet and a header flit of a current packet; and (2) using a Cyclic Redundancy Check (CRC) in the header flit to verify the payload flit of the preceding packet and the header flit of the current packet.

  • Patent number: 10097203
    Abstract: A CRC generator, a method for computing a CRC of a data packet, and an electronic system, such as a circuit board, are disclosed herein. In one embodiment the method is for computing the CRC of a data packet to be transmitted on a serial communications link having multiple lanes. In one embodiment, the CRC generator includes: (1) a CRC calculator configured to define a CRC calculation of a data packet in sequential order and perform parallelized computations, according to the sequential order and the multiple lanes, to generate sub-CRC values and (2) combination circuitry configured to combine the sub-CRC values to provide the CRC value for the packet.

  • Patent number: 9954984
    Abstract: A receiver, transmitter and method for enabling a replay using a packetized link protocol are provided. In one embodiment, the method includes: (1) transmitting a stream of packets including an untagged packet and (2) using synchronized counters to determine a sequence ID of the untagged packet, which is a corrupt/lost packet that needs to be retransmitted.
