Comment on Micron says driverless cars and robots will need 300GB of RAM
Omgpwnies@lemmy.world 1 day agoWith the current level of tech in a car, you’re already likely pushing 300GB in total. There’s dozens of high-compute ECUs doing all sorts of things, running some *nix OS and using anywhere from a couple GB to well… way more.
to reach full driverless capability, those will need to become more powerful, the software will require more memory, and the number of compute modules will likely increase as well for sensors and other stuff.
300GB IMO is probably a conservative estimate.
I’m not trying to sound angry at you, but I’m told I come off that way. So please let me start this with an advanced apology.
We have the esp32 in very common circulation. We have seen what is required to keep a thing fucking airborne, and it is so beyond what I thought was possible twenty years ago. And they did it with <1 gig.
No worries, nothing grouchy sounding there :)
My statement is sourced by me working in R&D in the automotive industry on these modules… an ESP32 does not come close to the amount of computing resources needed to move and process the absolute boat load of information required to make decisions for autonomous driving.
Flying around doesn’t need the same level of object detection, path-finding, decision making and so on that a vehicle that is capable of killing anyone in or around it needs. And on top, it has to be able to do that at highway speeds, without ever making a mistake - because of the killing everyone in or around it part.
Further, it needs to deal with all the random stuff all those people are doing around it all the time… again, without ever making a mistake.
So it needs to be able to see something, identify if it’s something it needs to be concerned about, figure out if it might be doing something that needs to be addressed, make a plan, then execute it… in like a few milliseconds. with a virtually unlimited number of potential obstacles, while obeying traffic laws, and still get the occupant to their destination.
Without killing anyone.
And that’s just the ADAS subsystem.
Yeah, I guess I didn’t take into account that airborne is easier considering encountering randomly moving objects.
But 300gigs is a bad number on at least 2 different levels.

The actual article (and the call it is reporting on, with statements from the CEO) says that 16GB is the average in new cars today. No need to make stuff up.
