Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does CPU Time consist of?
- Just clock cycles
- Clock cycles + memory stall cycles
- Only execution cycles
💡 Hint: Think about what happens when the CPU cannot access memory.
Question 2
True or False: A lower miss rate improves CPU performance.
- True
- False
💡 Hint: Consider the relationship between cache hits and CPU efficiency.

Challenge Problems
Push your limits with challenges.
Question 1
In a system where 25% of memory accesses result in a miss, and each miss incurs a penalty of 100 cycles, calculate the overall impact on CPU performance if the base CPI is 1.5.
💡 Hint: Follow the formula and apply realistic values from the problem.
Question 2
Analyze a scenario where memory access time spikes due to increased miss rates. How would this reflect on application performance over time in a real-time computing environment?
💡 Hint: Consider the compound effects of waiting on process requirements and time-critical applications.
