Is there a return address stack on the CPU (limited to memory on chip), or is it emulated in software at the assembler using regular RAM?

Yes.

  • Some processors do not have a stack (and need to emulate it using RAM for everything)
  • Some have a fixed size stack
  • Most use general purpose ram via a stack register
  • Some have a stack that is partially in CPU cache and partially in RAM.
