Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are designing a CPU architecture. Explain how you would manage the fetch, decode, and execute phases efficiently, especially in the context of handling multiple simultaneous interrupts.

💡 Hint: Consider how task scheduling in operating systems tackles multiple requests.

Challenge 2 Hard

What are the trade-offs between immediate and indirect addressing modes in CPU designs? Discuss the implications on instruction size and execution speed.

💡 Hint: Think about efficiency versus flexibility in CPU operations.
