Jul 26, 2014 at 22:42 comment added metacubed @JasonGoemaat This simple automation only has access to the top element of the stack. The first element has to be popped and stored in a register before it can access the second. There are other automata which use random access memory instead of a stack.
Jul 25, 2014 at 19:12 comment added Jason Goemaat Why do you need a register at all? If the processor can perform an operation on 1 register + 1 value on stack, why can't it perform an operation on 2 values on stack?

Jul 25, 2014 at 12:00 comment added Niccolo M. For completeness' sake, here's a sub question: do we need an unlimited stack size for "unlimited complexity"?
