The core is a UDP/IP hardware protocol stack. Designed for standalone operation, the core offloads the host processor from the task of UDP/IP encapsulation and enables media streaming with speeds up to 40Gbps even in processor-less designs.
Trouble-free operation is ensured through run-time programmability of all the required network parameters (local, destination and gateway IP addresses; UDP ports; and MAC address). The core implements the ARP Protocol, which is critical for multiple access networks, and the Echo Request and Reply Messages of the ICMP widely used to test network connectivity. It can use a static IP address or automatically request and acquire an IP address from a DHCP server. Finally, the core supports 801.1Q tagging, and is suitable for operation in a Virtual LAN.
The core is easy to integrate in systems with or without a host processor. Packet data can be read/written to the core via dedicated streaming-capable interfaces, or via registers mapped on an SoC bus.
Protocols, IPv4 without packet fragmentation, Jumbo and Super Jumbo Frames, ARP with Cache, ICMP (Ping), IGMP v3 (Multicast), UDP/IP Unicast and Multi
Up to four UDP channels
Run time programmable network parameters: Local, Destination and Gateway IP address, Source and Destination UDP ports, MAC address
Available pre-integrated with the Intel FPGA 40G Ethernet MAC core
Device Utilization and Performance
The silicon resources requirements depend on the core configuration. A quad channel core synthesizes to approximately 7,500 ALMs and requires 400k bits of memory, while a single channel core synthesizes to approximately 97,000 ALMs and requires 800k bits of memory.
To deliver a 40Gbps under the worst case scenario, the core needs to be clocked at 312.5MHz, however running the core at 200MHz should suffice to deliver 40Gbps in realistic UDP/IP traffic scenarios.
