NPAC FeatureComment
Processing offloadNetworking functions are offloaded to the NPAC, freeing up SoC cores to perform other tasks.
Multi-functionSupport multiple functions, including L3 (IP), L4, and VLAN routing, gateway, packetization, depacketization, encryption, decryption, authentication, and firewall filtering.
Programmable

Combination of dedicated hardware accelerators and programmable RISC-V cores allows customers to easily configure and customize networking functions.

Low power | low latency Fixed function hardware and high-speed packet bus reduce power and latency.
Packet routingL3 (IP), L4, and VLAN routing offload.
Packetization and de-packetization Packetization and depacketization offload; a direct packet bus connection to system memory reduces latency and increases throughput when SoC processing is required.
Firewall and packet filteringSupports access control list (ACL) filtering and packet inspections, routing traffic to authorized areas only.
Encryption, decryption, and authenticationDedicated, low-latency cryptographic accelerators support CANsec, IPsec, TLS, SecOC, and other cryptographic standards.

Graphic based

programming GUI

An intuitive, easy-to-program graphical model enables customization of NPAC functionality. A library of pre-defined and custom nodes maximizes supported use cases and decreases NPAC programming time.
Scalable architecture

Scale networking performance from zonal to central compute gateways on a common hardware architecture maintaining code compatibility.
