4. a) (3) Is the single-cycle data path an example of a Princeton (i.e., von Neumann) architecture or is it an example of a Harvard architecture? Explain your answer.

b) (3) Is the multi-cycle data path an example of a Princeton (i.e., von Neumann) architecture or is it an example of a Harvard architecture. Explain your answer.

c) (3) If the clock rate for the multi-cycle data path is 2 GHz, what is the theoretical peak MIPS rating for a program that runs on the multi-cycle data path and contains only instructions from our MIPS core instruction subset?
