D Question 1 4 pts Consider a computer that has a 3 GHz clock rate and a CPl of 1.5 a. What is performance expressed in instructions per second? x 109 b. If the computer execute a program in 10 seconds, what is number of cycles? x 10 c. What is the number of instructions executed? x 109 d. We are trying to reduce the execution time by 30% but this leads to an increase of 20% in the CPI. What clock rate should we have to get this time reduction? GHz (Preserve 2 digits after the dot)
