2.2 (12 pts) Consider two different machines, with two different instruction sets, both of which have a clock rate of 400 MHz. The following measurements are recorded on the two machines running a given set of benchmark programs. Determine the effective CPI, MIPS rate, and execution time for each machine. Also fill in the dark rectangles in the two tables (6 pts, 1 per square) Instruction Count Cycles per Cycles (millions) Instruction (millions) Instruction Type Machine A Arithmetic & Logic Load & Store Branch Others Totals (3 pts) CPIA: MIPSA: CPUA Time

Explanation / Answer

No. of Cycles = Instruction Count * Cycles Per Instruction

Cycles Per Instruction (CPI) = Total Cycles / Total No of Instructions

CPU = No of seconds per cycle

MIPS = (CPU / CPI ) / 1Million

CPU Time = No. of Cycles * CPU

CPIA = 40 / 18 =

CPUA = 400 MHz

CPUA Time = 400 * 40 = 1600 sec

MIPSA = (400 / (40 / 18) )/ 1000000 = 180 / 1000000 = 0.00018

38

CPIB = 38 / 22

CPUB = 400 MHz

CPUB Time = 400*38 = 1520 sec

MIPSB = (400/(38/22))/1000000 = (400*22)/(38*1000000) = 88/380000 = 0.00023
