Help you with what?

A new thread in Homework Help involves a few steps:

1) Post the problem you are working on.
2) Post YOUR best attempt to work YOUR homework problem.
3) Ask specific questions regarding what you are having trouble with.

Again, YOU need to show YOUR best attempt to do YOUR homework. This is Homework Help, not Homework Done For You.

You also aren't giving the complete problem statement because your thread title mentions the use of registers.

I know a fair amount about Verilog. But now you are adding yet more stuff that you haven't mentioned -- instead of a hardware design now it is apparently a Verilog assignment.

If you won't show any effort on your own part and won't even describe the problem in full, we can't do much for you.
