Challenge Problems

Push your limits with challenges.

Question 1

Consider a scenario where the micro-programmed control unit needs to handle an interrupt during instruction execution. How does it manage the current instruction state and ensure proper branching?

💡 Hint: Think about preservation of execution context and how branching plays into handling exceptions.

Question 2

Design a memory layout scheme that preserves the integrity of control signals, branching conditions, and instruction operations in micro-program memory. Explain your design choices.

💡 Hint: Reflect on the organization of data and what can cause conflicts during execution.
