Arkville DPDK IP Core
DPDK/AXI Aware Data Mover IP Core
Computational packet processing applications such as software-defined networking (SDN), network functions virtualization (NFV), machine learning, video transcoding, image and speech recognition, CloudRAN, and Big Data analytics may employ both wirespeed gateware functions on an FPGA in conjunction with fast operations performed in software on one or more host processor cores.
Arkville DPDK IP core from Atomic Rules provides a high throughput line-rate agnostic conduit between FPGA hardware and GPP software. Using industry-standard AXI interfaces on the FPGA side and DPDK interfaces on the software API/ABI side, Arkville provides an exceptional “out-of-the-box” solution for both hardware and software teams. Because Arkville was designed with the specific goal of accelerating and empowering DPDK, the performance is significantly higher than one of a naïve DMA implementation on an FPGA.

Block Diagram, Data Sheet and Product Details
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. 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.
