Quad SPI-3 to SPI-4 Link Layer Bridge


Newsletter Subscription

The Quad SPI-3 to SPI-4 Bridge Intellectual Property (IP) Core targets the programmable array section of the ORCA ORSPI4 FPSC and provides the Link Layer bridging function between one to four SPI-3 links and a SPI-4 link.

Features

  • Complete Quad SPI-3 to SPI-4 Link Layer Bridge Solution Based on the ORCA ORSPI4 FPSC
  • IP Targeted to the ORSPI4 Programmable Array Section. Implements Functionality Conforming to OIF-SPI3-01.0, Including:
    • Up to four full-featured SPI-3 link interfaces
    • Up to eight ports supported per interface.
    • Parameterizable Byte or Packet Mode selection
    • Configurable through the MicroProcessor Inter-face (MPI) ORCA 4 System Bus
    • Programmable parity type on SPI-3 bus
  • SPI-4 Functionality Supported by the Embedded Section of the ORSPI4, Including:
    • Standard 10Gbps physical to Link Layer interface
    • Support for "static" and "dynamic" alignment at the receive interface
    • Single-link and multi-link operation
    • SPI-4.2 transmit data protocol support logic
    • Embedded calender-based sequence port polling mechanism and bandwidth allocation for 256 ports
