the BMv2 behavioral model https://github.com/p4lang/behavioral-model,
* p4c-dpdk: can be used to target the DPDK software switch (SWX) pipeline
https://doc.dpdk.org/guides/rel_notes/release_20_11.html,
* p4c-ebpf: can be used to generate C code which can be compiled to eBPF
https://en.wikipedia.org/wiki/Berkeley_Packet_Filter and then loaded
in the Linux kernel for packet filtering,
* p4c-ebpf: can be used to generate C code which can be compiled to [eBPF](https://en.wikipedia.org/wiki/Berkeley_Packet_Filter)
and then loaded in the Linux kernel. The eBPF backend currently implements two architecture models:
[ebpf_model.p4 for packet filtering](./backends/ebpf/README.md) and [the fully-featured PSA (Portable Switch Architecture) model](./backends/ebpf/psa/README.md).
* p4test: a source-to-source P4 translator which can be used for
testing, learning compiler internals and debugging,
* p4c-graphs: can be used to generate visual representations of a P4 program;
for now it only supports generating graphs of top-level control flows, and
* p4c-ubfp: can be used to generate eBPF code that runs in user-space.
* p4c-ubpf: can be used to generate eBPF code that runs in user-space.
