In the microprogram for Mic-1, in iadd2, TOS is copied toH. Then there is the statement MDR=MDR+H as part of iadd3.
Question 1 - Why can't we suppress copying TOS to H and justdo MDR = MDR + TOS in place of MDR = MDR + H?
Question 2 - What would need to change in the Mic-1architecture for this to be possible? Would this changethe execution time of this instruction?
