NaNet is a modular design of a family of FPGA-based PCIe Network Interface Cards implementing low-latency, real-time data transport between its network channels and the the host CPU and GPU accelerators memories. The design feature a network stack protocol offloading module that operating in conjunction with a high performance PCIE Gen2/3 X8 core yields a low and predictable communication latency, making NaNet suitable for real-time applications. A reconfigurable processing module is also available to implement application-specific processing on inbound/outbound data streams with highly reproducible latency. As of now NaNet design has been specialized in the NaNet-1 (single 1GbE port) and NaNet-10 (four 10GbE ports) configurations employed in the GPU-based real-time trigger of the CERN NA62 experiment, and in the NaNet3 (four 2.5 Gbit optical channels) configuration adopted in the data acquisition system of the KM3NeT-Italia underwater neutrino telescope. Assessment of the real-time characteristics and performances of the resulting systems will be provided and analyzed.
