Challenge Problems
Push your limits with challenges.
Question 1
Analyze a Cortex-A processor that executes 50,000 instructions with a CPI of 1.5 and a clock cycle time of 3 ns. Calculate the execution time and discuss whether increasing processors to lower CPI would impact performance.
💡 Hint: Apply the execution time formula and think about how CPI affects workload management.
Question 2
Given two different processors with different architectures, one with a CPI of 1.2 and the other with a CPI of 2.5, analyze their efficiency. What factors could lead to such differing CPI values?
💡 Hint: Consider aspects like instruction sets and microarchitecture.
