SPAUI Code for Altera Stratix II GX FPGA

Dune Networks announced the availability of SPAUI code for Altera’s Stratix II GX FPGAs. Dune and Altera worked closely together to ensure SPAUI interoperability between Dune’s Next Generation devices and Altera’s Stratix II GX FPGA family with embedded multi-gigabit transceivers.

SPAUI combines the benefits of both XAUI and SPI4.2 standards into a single SERDES-based interface supporting MAC/Framer, NPU and Traffic Management interconnection requirements. The interface extends the XAUI interface by introducing channelization, packet interleaving, and refined flow control. SPAUI is implementation-friendly, supported easily by SERDES-based FPGA devices, and is backward compatible to the standard XAUI. The flexibility, simplicity and robustness of SPAUI make it an ideal interface for dense 10Gbps networking applications. Any vendor implementing XAUI can easily support SPAUI, foregoing the need for special encoding or any other major change in silicon.

The Altera-based SPAUI implementation is available at both multiples of 3.125 Gbps and 6.25 Gbps speeds and enables flexible bundling to create higher speed links. The SPAUI memorandum and FPGA implementation are now available upon demand from Dune Networks.
