Algo-Logic Systems' ultra low latency (ULL) 10GE MAC minimizes roundtrip latency by several hundred nanoseconds as compared to vendor supplied IP cores. It is compatible with Altera's PHY to make a complete solution: PHY+MAC. The design implements 10GBASE-R MAC and PCS (Physical Coding Sub-layer) functionality in an FPGA by using logic optimized for latency. The ULL PHY+MAC supports SERDES rates of 10.3125 Gbps while bypassing all PCS and excessive buffering features. The MAC interfaces to user logic via the 64-bit Avalon-ST bus or AXI4-Stream standards. The Ethernet Frame Check Sequence (FCS) within the transfer is automatically added in the transmit direction; the FCS is checked, indicated, and removed in the receive direction. The only padding done is on the transmit side (Tx) if the transmitter MAC sees fewer than 60 bytes. On the receive side (Rx), the MAC passes the packet that it receives without change.


    Device Utilization and Performance

    Device utilization on Stratix V A7 is: 1. Wire to wire latency: 89.6nS 2. Registers: 1915 3. Logic utilization: 1689 ALMs 4. Block memory bits: 0
