	 Hello Professor Patt,
	 
	 As I went through the 2008 exam 2, I ran across the question involving 
	 the data path that made me realize that I don't know the data path as 
	 well as I should be. I was wondering how the MARMUX, ADDR1MUX, and 
	 ADDR2MUX is used to compute an instruction.
	 
	 Thanks for your time,

I have some questions for you:

1. You know that the computer processes each instruction, yes?
2. What is it that does that processing?

Once I get those answers from you, we will move on to the next step.

Incidentally, were you at the review session last night.  We went over this 
problem in great detail.

Good luck on the exam tomorrow.
