9 55 Machine A, before optimization, takes 20 seconds to execute a given benchmark program. After optimization it takes 15 seconds. What is the speedup? 10 8$ Consider the following computer system (same as in question 9) -load/store operations take 5 cycles and make up 30% of the dynamic instruction count -jump instructions make up 15% of the dynamic instruction count and take 4 cycles -all other instructions take 2 cycles What is the average CPI? 12pt V | B I u A 2 PA
