Why would you need 18 CAN interfaces?
daqq:
Ti released a chunky processor: https://www.ti.com/lit/ds/symlink/am69.pdf
With a GPU, 8 big ARM cores, 4 smaller ARM cores, 4 DSP cores it seems quite powerful. My question is, in a real world scenario, where do you need 18 CAN-FD interfaces? Isn't the point of a bus that you connect more things to it?
Not complaining, just would like to know the monstrous application that has such demands.
Jeroen3:
Cars have more than one CAN bus. CAN bus is limited in the number of nodes if there is also a need to a usable amount of communication.
mikeselectricstuff:
Multiple buses for more bandwidth?
Whales:
I was going to say that keeping multiple, isolated can busses is good for security & safety (eg don't put the entertainment system on the same bus as the abs brakes or the pedal position pots). But then I realised that if you connected them all to this unit you would violate that principle anyway.
GPU accelerated ABS.
Psi:
I can imagine a modern electric car might need that number of CAN buses.
Especially when you start to think about adding self-drive with all the cameras / radar / lidar etc..
You want some separation between different systems.
