2. The remaining problems in this exercise assume that datamemory is all zeros andthat the processor’s registers have the following values at thebeginning of the cyclein which the above instruction word is fetched:
1) For each Mux, show the values of its data output during theexecution of this instruction and these register values.
2) For the ALU and the two add units, what are their data inputvalues?
3) What are the values of all inputs for the “Registers”unit?
