Consider a non-pipelined, non-parallel, sequential machine. The CPU executes each machine instruction in a series of small steps as indicated in the list of Section 2.1.2 (page 58) of the textbook. Explain precisely what needs to be done at hardware level in Step (6) If the machine instruction currently being executed is an unconditional "branch" instruction in the form: JUMP 8000. State precisely which of the four registers located in the CPU and mentioned in the previous question are consulted and/or modified and how. What is the purpose of Step (2) in the list of Section 2.1.2? What would happen if this step is completely omitted? Is it possible to move Step (2) and place it after Step (6) but before Step (7) Consider the hypothetical machine discussed in class.
