P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 2.5 GHz clock rate and a CPI of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 2.2. a. Which processor has the highest performance expressed in instructions per second? b. If the processors each execute a program in 10 seconds, ± nd the number of cycles and the number of instructions. A. Highest Performance P1=> 3GHz / 1.5 = 2 * 10^9 ips P2 => 2.5GHz / 1.0 = 2.5 * 10^9 ips P3=> 4GHz / 2.2 = 1.82 * 10^9 ips p2 has the highest ips B. Cycles P1=> 3GHz * 10 = 3 * 10^10 c P2=> 2.5GHz * 10 = 2.5 * 10^10 c P3=> 4GHz * 10 = 4 * 10^10 c 1 / 1 pts Question 2 An abstract interface between hardware and the lowest-level software is called: north-bridge memory interface instruction set architecture Correct!

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
