Product Operation

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.

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.
