RDMA IP Core for RoCE v2 from Grovf
BittWare Partner IP Core RDMA Low-Latency RoCE v2 at 100Gbps The GROVF RDMA IP core and host drivers provide RDMA over Converged Ethernet (RoCE v2)
Seamlessly transport data between FPGA logic and host memory at up to 60 GBytes/s (480 Gbps) in each direction. Arkville provides a high-throughput, low-latency conduit between host memory and FPGA fabric logic, offloading CPU core usage, eliminating memory copies, and improving overall efficiency.

As shown in the block diagram, Arkville has both a hardware and software component. The hardware component is an IP core that resides in the FPGA, producing and consuming AXI streams of packets making ingress or egress. The software component is a DPDK PMD “net/ark”, the Arkville DPDK poll-mode driver. Arkville is a conduit between FPGA logic and Host user memory for bulk data movement or individual packets.
Together, an Arkville solution looks to software like a “vanilla” line rate agnostic FPGA-based NIC (without any specific MAC). DPDK applications do not need to change significantly in order to enjoy the advantages of FPGA hardware acceleration.
