9. What is the latency caused by inter-subsys. communication via Ethernet or USB/mPCIe ?

When inter-subsys. communication is Ethernet, typically it is less than 1ms by an off-the-self solution. 1ms delay is about a distance of 3.89cm when a vehicle moves in 140km/h.

When inter-subsys. communication is mPCIe (USB), typically it is less than 2ms by an off-the-self solution.

The solutions provided above are the tradeoff between having acceptable performance and enabling V2X technology for different industries and on different platforms easily. If you have concerns about this, it is welcome to have a project to co-work with Unex.
