What is a control signal in the context of a CPU?
Think about what helps in coordinating tasks inside the CPU.
Define a finite state machine (FSM).
Remember, it involves conditions that lead to state changes.
What is the primary function of control signals in a CPU?
Consider what allows the CPU to manage various tasks.
True or False: A finite state machine can only transition between two states.
Think about how many paths an FSM can have.
Create an FSM diagram for an instruction cycle involving FETCH, DECODE, and EXECUTE states. Ensure to indicate conditions for transitions.
Think about what confirms the completion of each step.
Analyze a hypothetical scenario where a CPU wait state occurs. Discuss how this affects the instruction cycle and what signals are likely at play.
Consider how external factors can pause normal operations.
