SPAUI MAC Core (MorethanIP)

支持器件系列

• Virtex-5 FXT
• Virtex-5 LXT

The SPAUI Protocol provides a proprietary open mechanism, originally from Dune Networks, to interconnect MAC/Framer, Network Processor, and Traffic Manager. SPAUI combines the benefits of both XAUI and SPI4.2 to support additional services such as per channel flow control segmentation and burst traffic.The SPAUI MAC Core implements, on the Client side, a flexible simple 64-Bit FIFO interface designed to be seamlessly connected to standard Core (e.g. SPI-4) or customer applications. The SPAUI MAC can be field configured to operate in standard IEEE802.3ae mode or to implement the SPAUI extended services.

关键特性

• Full MAC layer and Reconciliation sub-layer implementation compliant with IEEE802.3ae specification.
• BCT Bytes CRC-4 generation and checking with Burst and segmented frames support.
• Supports for SPAUI in-band extended class based flow control frames, Link Level Flow Control (LLFC) with BCT Bytes and packet agnostic pause frame format.
• Implements Out-of-Band status interface with programmable calendar and synchronization parameters.
• Supports standard Ethernet Pause Frame (802.3 Annex 31A) termination and generation with programmable Quanta.
• Deficit Idle Counter (DIC) for optimized performance with minimum IPG for LAN applications.
• Programmable frame maximum length providing support for any frame (e.g. Jumbo Frame or any tagged Frame).
