Product Description

Vitis Networking P4 is a high-level design environment to simplify the design of packet-processing data planes that target FPGA hardware. It is a tool to convert the P4 design intent into an AMD FPGA design solution. It allows programmers to build new data planes by explicitly specifying the header and packet processing. It supports processing engines with specialized behavior, to include: parsing engines, match-action engines, and deparsing engines, each generated according to an application-specific requirement. To implement a P4 design the compiler maps the control flow onto a custom data plane architecture of engines. This mapping chooses appropriate engine types and customizes each of them based on the P4-specified processing.

Key Features and Benefits

Construction of hierarchical Vitis Networking P4 systems, consisting of a large variety of different types of engines including: Parsing, Deparsing, and Match-Action engines

Parsing engines extract header information from packets
Deparsing engines manipulate the contents of packet headers by inserting, modifying, or removing packet data
Action engines are designed for manipulating metadata that might be determined from packets or data originating externally or internally from some other engine
Look-up engines instantiate memory search IP cores generated from a library for packet processing including: exact match (BCAM), longest-prefix match (STCAM), ternary match (TCAM), and RAM (direct) tables
Systems resulting in high performance hardware implementations, achieving up to 200 Gb/s
Support for different clock domains so that engines can run at one of the following frequencies:
- Line rate of the packet data bus used typically for engines reading or modifying packets
- Packet rate used for functions that occur once per packet such as an individual look-up
- Control rate which is the speed of the memory-mapped control interface for controlling and configuring engines
Software available for high level system simulation of the design prior to running RTL simulations
System backpressure capability is automatically generated including the insertion of buffers providing dataflow synchronization for engines. This capability enables backpressure of the packet bus for momentarily pausing packet processing
AXI-Stream signaling protocol for packet interfaces
