the binary instructions. Our program is simply two nested “do nothing” loops, with a short informative message printed on each exit of the inner loop. We can control the overall execution time of the program by varying the outer loop count, while fixing the inner loop count at 255. We have three different experiment executions, varying the outer count from 256 to 4096 to 65,536. Thus the total number of inner loop executions are 216, 220, and 224 respectively. An abbreviated version of the program is shown below in figure 4.
