Part 3: CPU Performance and Pipelining 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 characteris- tics result: 1. Clock Frequency Performance CPU Time (secs) 12 x (MHz) (MIPS) VAX 11/780 IBM RS/6000 25 18 The final column shows that the VAX required 12 times longer than the IBM mea- sured in CPU time. What is the relative size of the instruction count of the machine code for this benchmark program running on the two machines? a. b. What are the CPI values for the two machines
