So, one high-performance, high-power, general-purpose processor to handle the foreground task, and a bunch of low-power processors for background tasks.

Looks like ARM got it right with its big.LITTLE architecture. :)

The low power processors are not general purpose, they are fpga's, they get trained and then are highly optimized at their task.

And they stay in the brain even when not used. You can ride a bike or play a piano years after stopping.
