A debate started in this thread about the viability of using recycled chips from PCs, smartphones and other advanced electronics to replace the dependence of car manufacturers on custom built silicon.
So I figured I’d pose the question here.
Recently it’s made headlines that there’s a growing shortage of computer chips for the automotive industry. The big manufacturers have shifted almost all of their production lines to deliver chips to Apple, Samsung and the other major electronics companies at the expense of the auto makers who don’t represent a particularly important market segment in relative terms.
What specifically makes automotive chips so different and so much more demanding than smartphone or PC chips? Setting aside the software and firmware, which can be rewritten and recompiled, why couldn’t a automotive engineer with sufficient time and money re-engineer their platform to use a bunch of last-generation smartphone chips to power their ECUs, PCMs and infotainment systems?
Calculations are calculations. Bandwidth is bandwidth. Silicon is silicon. They stuff comes off the same fabs, so what’s so special about car chips?
