2 cards from this section. Quick, good the night before a test.
Define CPU Time.
Think about what factors contribute to this time.
What is a miss rate?
Consider the performance aspect of memory access.
What does CPU Time consist of?
Think about what happens when the CPU cannot access memory.
True or False: A lower miss rate improves CPU performance.
Consider the relationship between cache hits and CPU efficiency.
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.
Follow the formula and apply realistic values from the problem.
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?
Consider the compound effects of waiting on process requirements and time-critical applications.
