Question 1 3 pts A program executes 200 billion instructions. It executes on an IBM processor that has an average CPl of 1.2 and a clock frequency of 3.2 GHz. 1. How many seconds does the program take to execute? 2. What is the cycle time of this IBM processor (in ns)? 3. Assume that an ARM processor takes 100 seconds to execute the program. What is the speedup provided by the IBM processor, relative to the ARM processor
