Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A processor operates at a clock speed of 1.5 GHz with an IPC of 6. Calculate the maximum instructions it could theoretically execute in 30 seconds.

💡 Hint: First calculate per second, then multiply by 30.

Challenge 2 Hard

Analyze the implications of reducing IPC by 20% in a processor with a baseline IPC of 4. What changes in instruction throughput can be expected?

💡 Hint: Think about how overall instruction numbers change and impact performance.
