[Cs35101] More clarification on hw6 q1

[Dianne Foreback]

Hello Computer Architecture Class,

I was asked for clarification on the multiplexers.

I added red lines to the figure posted next to the homework assignment to ID the names of the muxes. 

The verbiage at the top of the figure explains the functionality of the mux.  Assume 0 is at the top of the mux and 1 is at the bottom.  So, 0 selects the data memory as input to the reg file and 1 selects the Alu as input to the reg file.

Also remember that the blue line titled ALU operation selects the operation that the Alu performs and this is two bits.

Hope this helps,
Dianne
