Challenge Problems
Push your limits with challenges.
Question 1
A developer needs to calculate the total execution time for their application that has an instruction count of 1000, a clock cycle time of 0.005 seconds, and a CPI of 2. Calculate the total execution time and analyze the impact of reducing the CPI to 1.5.
💡 Hint: Use the execution time formula to assess the changes.
Question 2
Compare two Cortex-A processors: Cortex-A75 and Cortex-A53 in a power-constrained environment. Discuss how each design focuses on power efficiency versus high performance.
💡 Hint: Think about use cases for both types in real scenarios.
