5 cards from this section. Quick, good the night before a test.
Define what CPU Time means.
Think about all components that contribute to CPU performance.
What does the term Memory Stall Cycles refer to?
Consider situations when the CPU is inactive.
What is the main component of CPU time calculation?
Remember the formula discussed in class!
True or False: A higher miss rate results in better performance.
Think about the impact of memory retrieval delays.
Given a CPU clock speed of 3 GHz, calculate the cycle time and analyze the effective CPU Time using a base CPI of 1.5 with 25 memory stall cycles.
Remember to convert GHz to its corresponding cycle time!
Examine a scenario where a program’s memory miss rate is reduced from 15% to 5%. Calculate how this change impacts overall effective CPI given the same miss penalty and overhead.
Consider how significantly even small percentages affect overall performance!
