Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a scenario where a CPU needs to handle multiple interrupts but must ensure data integrity during a transaction, explain how you would implement EI and DI effectively.

💡 Hint: Consider the timing of each operation and the need for data integrity.

Challenge 2 Hard

Design a small assembly code snippet utilizing HLT, DII, NOP, and SIM to illustrate their functions in a control flow.

💡 Hint: Think about a sequence of operations that require managing interrupts and execution flow.
