2 [Instruction Execution Rate] [10 points] Early examples of CISC and RISC design processors are the VAX 11/780 and the IBM RS/6000, respectively. Using a typical benchmark program, the following machine characteristics result: The final column shows that the VAX required 12 times longer than the IBM measured in CPU time. Questions: a. What is the relative size of the instruction count (IC(RS)/IC(VAX)) of the machine code for this benchmark program running on the two machines? b. What are the CPI (Clocks per Instruction) values for the two machines (processors)
