  • Patent number: 11343203
    Abstract: This invention discloses a hierarchical switching fabric and deadlock avoidance method for ultra high radix network routers. The hierarchical switching fabric comprises a network-on-chip and K multi-port components. The multi-port component comprises a port module configured to receive packets by a high speed serializer/deserializer, code and format the packets, send the packets to a corresponding hyper packet module after coding and format conversion, and send the packets sent by the hyper packet module to the network; and the hyper packet module configured to perform protocol processing for the received data link level packets, discard illegal packets, forward legitimate packets to the network-on-chip, perform data error correcting, format conversion and channel mapping for the packets received from the network-on-chip, and send the packets to the corresponding port module.

  • Patent number: 11265400
    Abstract: This invention discloses a multimode interconnection interface controller for a converged network, which comprises a SERDES element responsible for serial/parallel conversion, a LANE_TXCLK element responsible for generating a transmit clock, a SERDES initialization element responsible for link training and rate negotiation, and a PCS_EB coding element and an PCS_AF coding element responsible for physical layer coding of messages. The link training and rate negotiation are completed automatically via the shared SERDES initialization element. More universality and flexibility are provided for interconnection chip design by the PCS_EB coding element. The PCS_AF coding element is provided to reduce message penetration delay. The multimode interconnection interface controller is integrated in a single chip. Through flexible configuration, the single chip can meet transmission requirements of dedicated high speed networks and Ethernet networks.

  • Patent number: 11244218
    Abstract: The present disclosure provides a polarized Raman spectrum-based nano barcode smart label, including: a substrate and a nanoparticle coding layer that is provided on the substrate and can be coded by polarized Raman spectrum coding, wherein the nanoparticle coding layer that can be coded by polarized Raman spectrum coding is a mixed layer including a plurality of nanomaterials having different Raman characteristic peaks; under different polarization detection states, the Raman characteristic peaks can exhibit coding characteristics that are totally different from those under a non-polarization detection state and are distinguished from those of a conventional Raman peak position, so as to achieve spectral characteristics for multiple coding. During use of the smart label of the present disclosure, a corresponding nano barcode detection system is used to detect a brand label provided with the encoded nanoparticles to obtain coding information of the brand label.
