What is an interrupt?
Think about how computers respond to external events.
What does the program counter do?
Consider how sequential execution is tracked.
What happens when an interrupt occurs during instruction execution?
Consider the role of interrupts in context switching.
Is the Instruction Cycle Code (ICC) used to track the phase of instruction execution?
Think of how multiple phases are managed in instruction processing.
Design a simple scenario using hardware interrupts in a home automation system. Explain how it handles multiple events efficiently.
Think about the need for prioritization in safety-sensitive environments.
Evaluate the consequences of allowing interrupts during the execution of critical instructions. Discuss implications for both system stability and security.
Consider how essential it is to maintain control during sensitive processes.
