Yes, I actually said this in my original post: Arm BIG.little works, which is what M1 is, and embedded works well, which are SoCs. It is much more difficult in AMP systems that aren't necessary only the same die, like automotive Tier 1 products.
Hmm, I thought big.LITTLE implied that only one of the cores was active at once and all the tasks migrated from one to the other. M1 doesn't do that, all cores can be on all the time and they just start on one of them depending on priority.
