Well, most of us remember our lessons from our coursework, so there's 
not much chance we'll do your homework for you.  Most real machine code 
that I've seen only uses one stack for both local variables and the 
frame pointers.  I don't know where you get two stacks from.

Since your specification sounds hookey to me, I'd ask you to ask your 
instructor what is really going on.  Without understanding the exact 
specification it's impossible to say what is really going on here.
