2.3 (5 pts) 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 Processor Clock Frequency Performance CPU Time MHz) MIPS) Secs 12 x VAX 11/780 IBM RS/6000 25 18 The final column shows that the VAX required 12 times longer than the IBM measured in CPU time (3 pts) What is the relative size of the instruction count of the machine code for this benchmark program running on the two machines? You'll have to express the # instructions as a formula that includes MIPS and CPU Time a. 11/780 Ratio: # Instructions run by RS/6000 (2 pts) What are the CPI values for the two machines? CPI for RS/6000 b. CPI for 11/780 Note: You may have written the test program in a high-level language like C that was run on both of these machines. So why the big difference? HLLs get converted to assembly and then to machine language on the way to the CPU, which changes the number of instructions according to the ISA the particular CPU supports. That is why the same benchmark program can result in a sometimes dramatically different number of instructions being executed by different CPUsStep by Step Solution
