4 cards from this section. Quick, good the night before a test.
What is an interrupt?
Think of a scenario where something demands immediate attention.
What does the Program Counter do?
Consider what happens when a CPU executes multiple instructions in sequence.
What is the primary purpose of an Interrupt Service Routine?
Consider what the CPU does when it receives a signal it cannot ignore.
True or False: The Program Counter must be incremented after every instruction before checking for interrupts.
Think about the order of operations during instruction processing.
Design a hypothetical CPU flow and describe what happens in detail when an interrupt occurs during the execution of multiple instructions.
Outline your flow step-by-step to visualize the CPU state transitions.
Assume you have a set of instructions executing, and an interrupt occurs while processing a complex operation. Discuss the potential implications of this on instruction integrity.
Think about what happens if you forget to save your place in a book before being interrupted.
