The DB-UDP-IP-40GbE-AMBA is a UDP/IP Hardware Stack / UDP Off load Engine (UOE) with low latency, high-performance targeting 40 & 10 GbE network links. The DB-UDP-IP is a Verilog SoC IP Core targeting Intel/Altera and Xilinx FPGAs and ASIC/ASSP devices.
The image below depicts the UDP/IP Hardware Stack SoC IP Core embedded within an Altera / Xilinx FPGA device, connected on one side to a 40 GbE Ethernet MAC, and on the other side to the user application within the FPGA (i.e. either the FPGA logic fabric or embedded host processor).
