3. Early examples of CISC and RISC design are the VAX 11/780 and the IBM RS/6000, respectively. Using a typical benchmark program, the following machine characteristics result: Clock Frequency Performance Processor CPU Time (MHz) (MIPS) (secs) Vax 11/780 5 1 12 x IBM RS/6000 30 18 3x The final column shows that the VAX required 12 times longer than the IBM measured in CPU time. a. What is the relative size of the instruction count of the machine code for this benchmark program running on the two machines? b. What are the CPI values for the two machines
