ANIC Shell: Achronix Network Infrastructure Code
In anticipation of our demo at SmartNICs Summit 2023, here's a demo overview into Achronix's Ethernet network shell (ANIC) - a full ethernet data path built on top of the Speedster7t FPGA from data receive to data transmit at speeds up to 400G. In this video, we introduce the Achronix ANIC Networking Shell, a modular Ethernet SmartNIC that provides customers with a fully functional Ethernet datapath built on the Achronix SpeedsterAC7t1500 FPGA. The ANIC provides modular components such as Packet Engine, FIFO Buffer, Header/Parser, Rules Engine, Flow Processor, and DMA Engine that customers can select to provide the optimal datapath for their SmartNIC solution. In addition, over 50% of the Speedster7t FPGA is available for accelerating a customer’s network applications. We cover each modular element and the Achronix 2D NoC, which accelerates data transfers across the FPGA and enables customers to significantly reduce their solution design time. Director of Product Marketing, Ron Renwick, showcases our Achronix Speedster7t and its features, flexibility, and secret sauce (2D Network-on-Chip) to enable high-performance network data acceleration.

Demo: PCIe Gen5 x16 Running on VectorPath Accelerator Card
Achronix engineers show how to link the VectorPath Accelerator Card with Speedster7t FPGA to a PCIe Gen5 x16 host and read/write to GDDR6 memory via the full-chip two-dimensional Network on Chip (NoC). The NoC routes data from any of the high-speed interfaces to the core fabric within the FPGA at 2GHz without consuming any of the FPGA logic resources.

Demo: Achronix Speedster7t 2D NoC vs. Traditional FPGA Routing
This demonstration compares an FPGA design utilizing Achronix Speedster7t 2D Network on Chip (NoC) for routing signals with the FPGA device, versus using traditional FPGA routing. The 2D NoC provides a 40% reduction in logic resources required with 40% less compile time needed versus using traditional FPGA routing. Speedster7t FPGAs are optimized for high-bandwidth workloads and eliminate the performance bottlenecks associated with traditional FPGAs.

Achronix VectorPath Accelerator Card Uses PCIe Gen4 x16 to Communicate with AMD Ryzen PC
In this demonstration, the Achronix VectorPath™ accelerator card connects to an AMD Ryzen based PC using PCIe Gen4 x16 interface. The host PC issues commands to have the Speedster™7t FPGA on the VectorPath accelerator card write and read to external GDDR6 memory on the board. These data transactions are performed using the Speedster7t FPGA’s 2D network on chip or NoC which eliminates the need to write complex RTL code to design the host PC to GDDR6 memory interface.

See 400 GbE Running on a Speedster®7t FPGA from Achronix
400GbE is required for next-generation, high-performance networking applications. In this video, Achronix demonstrates 400GbE connectivity on a Speedster7t FPGA integrated into a VectorPath™ PCIe accelerator card. The demonstration shows 400GbE traffic generated within the FPGA and transmitted across the FPGA’s 2D network on chip or NoC to the Ethernet subsystem. The 400GbE traffic is then looped back and checked within the FPGA fabric to compare to the original data stream.

An FPGA-Based Solution for a Graph Neural Network Accelerator
Graph Neural Networks (GNN) drive high demand for compute and memory performance and a software only based implementation of a GNN does not meet performance targets. As a result, there is an urgent need for hardware-based GNN acceleration. While traditional convolutional neural network (CNN) hardware acceleration has many solutions, the hardware acceleration of GNN has not been fully discussed and researched. This white paper reviews the latest GNN algorithms, the current status of acceleration technology research, and discusses FPGA-based GNN acceleration technology.
