Yes, exactly, and it is for those other purposes that you want these
device cores to operate on the same ISA as the big cores. This way if
anything goes wrong, you can simply lob the code back to a CPU centric
core and finish the job.

If the design has P-cores and E-cores, both will have the same *pair*
of ISAs.

Code written in the big ISA will run on both kinds of core, and code
written in the little ISA will also run on both kinds of core, but use
less resources on whichever core it is placed.

So I won't have _that_ problem.

Each core can just switch between compute duty with N threads, and I/O
service duty with 4*N threads - or anywhere in between.
