Anders Arnholm - Embedding Linux for an Automotive Environment (pt 2/2)
Part 2/2. Part 1 here:
Running Linux on an embedded node in the automotive environment adds a number of new challenges that have to be addressed. One of the problems we have been working on is start-up times. We have trimmed the start-up time of the Linux kernel in less than 0.2 seconds on low end hardware. This presentation will look into and discuss some of the trade-offs we did to get the system starting up quicker on a limited hardware.
In an automotive environment many systems have to have there communication up within factions of a second, as the car get more complex more CPU power is needed in many different places. Traditional automotive solutions have been using two CPU’s on each node one small quick starting to handle the communication and one for the applications. If only one CPU can get the main applications starting quick enough that can make the hardware both simpler and cheaper.
