5. A popular app takes 10 seconds to execute on a 10 watt smartphone A, and it takes 9 seconds to execute on a 12 watt smartphone B. The app is a bigger drain on the battery on which smartphone? (10 points) 6. A processor running at 2.5 GHz consumes 60 W of dynamic power and 15 W of leakage power. It briefly enters Turbo-boost mode and operates at a frequency of 3.0 GHz. How much dynamic power and leakage power does the processor consume in Turbo-boost mode? (15 points) 7. System A has two processors. Program X takes 10 seconds to execute on one of the processors. Program Y takes 10 seconds to execute in parallel on the other processor. System B has a single processor that can execute only one program at a time. Program X takes 6 seconds to execute on this processor. Program Y takes 6 seconds to execute on this processor. Which system would you pick if you cared about overall system throughput? (15 points) 8. A program executes 100 billion instructions. It executes on an IBM processor that has an average CPI of 1.1 and a clock frequency of 4.0 GHz. How many seconds does the program take to execute? What is the cycle time of this IBM processor? Assume that an ARM processor takes 30 seconds to execute the program. What is the speedup provided by the IBM processor, relative to the ARM processor? (15 points) 1. Long-Term Treasury Bonds currently are selling at yields to maturity of nearly 8%. You expect interest rates to fall. The rest of the market thinks that they will remain unchanged over the coming year.
