So to tie this in to an application of these chips: Smartphone that has this - when idle (no phone calls, user is either not using or just looking at static screen such as e-reader or non-interactive web page) only low power chips run, doing the bare minimum housekeeping tasks, updating the screen, etc. When something happens, the low-power chips wake up the more powerful chips and hand off the task to them. Is that the basic idea? Intel's POV seems to be to have 1 powerful CPU with different power states, while ARM is explicitly breaking up the power levels with different CPUs on the same SoC.
