You are correct. It's on the same piece of silicon NOW. My original point is still good. I don't understand why there is a focus on a minor detail of the physical layout of the chip.
Correcting my original statement. "The CPACF is a PIECE OF THE CP that runs in lockstep with the CP that invokes it. So, it is does cost general CP but much less than implementing it in millicode."
