10 & 25Gbit/s Ethernet UDP/IP Hardware Stack for FPGAs
The Chevin Technology UDP/IP is an ultra-low latency IP core that offers fast transport layer Ethernet data transfer. Chevin Technology's UDP/IP simplifies the integration of the UDP protocol into any Xilinx FPGA at rates of 10 & 25 Gbit/s.
Ultra-low latency is achieved by offloading frame assembly and hardware accelerated checksum calculation for UDP datagrams.
This allows user data to take the shortest and lowest latency path to and from wire.

Benefits
- Chevin Technology’s 10G & 25G UDP Ethernet IP is FPGA Synthesisable EndPoint with Checksum Offload for ultra low-latency connectivity.
- The 10G & 25G UDP IP cores simplify FPGA integration of an ultra fast UDP/IP layer in any FPGA by handling the complete Ethernet frame assembly.
- A simple AXI4 streaming interface is all that is required to start sending and receiving UDP datagrams, and only the “user data” payload is exchanged between the application and the UDP block. For a single port application the port number can be set to a constant, hard coded or software configurable. A multi- port application is supported by a single UDP IP core by using the udp_port sideband embedded in the streaming interface.
