Isn't that what mainly differentiates Harvard from Von Neumann?

• immibis 2y ago
  No. They store code and data in separate address spaces. That isn't the same as storing code addresses and data addresses in separate parts of the data space.

    Yes. And all four combinations of Harvard / von-Neumann X single stack / double stack are potentially viable options. Btw, I think Forth has a separate data stack and return address stack?

      Yes. You can also freely use the return stack, IIRC, so long as you don't mess up a return itself.
