The nxTCP – Ultra low latency edition overview:
High Performance Computing
TCP IP CORE
- Best-in-class ultra-low latency from wire to user’s logic.
- 10G Ethernet connectivity. Maximum bandwidth delivered.
- Full RTL Layers 1, 2, 3 and 4, which include Enyx proprietary ultra-low latency full hardware TCP/IP, ARP, and ICMP implementations.
- Compatible with the Enyx ultra-low latency MAC/PCS IP core.
- Clock configurable at up to 350 MHz, for improved latency results.
- Easy to use standardized Avalon and AXI-4 interfaces.
- Multiple instances per FPGA and multiple logical interfaces per instance, each of them with a unique IPv4, MAC address, VLAN ID, Gateway and Mask.
- Up to 128 TCP sessions per instance, each of them configurable dynamically in server or client mode.
Available FPGA providers:
