GuardKnox and Lattice have partnered to provide a cost-effective and low-power solution for the automotive market that implements CommEngine™’s AUTOSAR PDU Routing capabilities in Lattice’s leading FPGA product suite. Lattice is a leading automotive FPGA manufacturer committed to providing on-chip security and flexible development tools for cost-effective programmable devices. The partnership brings the flexibility of GuardKnox’s CommEngine™, a highly-integrated communication engine, together with the power of Lattice FPGA solutions. 


Vehicles are transitioning to the next generation of E/E architecture, such as Zonal Architecture, characterized by fewer, but more powerful, ECUs that leverage a high-speed, multi-gigabit backbone interface that require secure communication to properly operate the vehicle. 

As messages in a Zonal Architecture must go through several ‘hops’ to arrive at their destination, vehicles require the minimum possible latency for communication routing to maintain safety and security, especially for mission-critical applications such as ADAS, break-by-wire, etc.  

GuardKnox’s CommEngine™ provides ultra-low latency communication capabilities even in complex scenarios and with high-bandwidth interfaces. 

Use cases


Sub-Zonal CommEngine™

Localized aggregation of low-bandwidth interfaces into a single high-bandwidth Ethernet, such as in a sub-zonal door module.


Zonal CommEngine™

Routing between low-speed and high-speed interfaces; additional computation cores MCU/CPU/GPU can be added according to application needs.


CommEngine™ as part of HPC Connectivity

CommEngine™ can be integrated into High Powered Computes to interconnect high-bandwidth backbone, sensors, and gateways.
