2 cards from this section. Quick, good the night before a test.
What does the Program Counter (PC) do?
Think about instruction flow in a program.
What does an interrupt do?
Consider what happens when a device needs attention.
What value does the Instruction Cycle Code (ICC) take during the fetch phase?
Recall the corresponding ICC values for each phase.
True or False: The Program Counter (PC) is not involved in the process of interrupt handling.
Think about what needs to be saved during an interrupt.
Design a hypothetical CPU that uses a three-bit Instruction Cycle Code and describe its phases.
Think about how adding more bits to the ICC might help manage more phases.
Consider a scenario where an interrupt occurs while the CPU is in the decode phase; how would your system manage the state?
What steps need to happen to ensure that data can be retrieved?
