19.2. Finite State Machine for Different Instructions

Try these first

1. 1.

   What is a finite state machine?

   Hint

   Think about how computers manage different states.

2. 2.

   Name one control signal used in the FSM.

   Hint

   Recall signals that guide instruction execution.

3. 3.

   What does MFC stand for?

   • Memory Fetch Control
   • Memory Function Complete
   • Memory Final Control

   Hint

   Focus on memory operation signals.

4. 4.

   True or False: An unconditional jump relies on flag conditions.

   • True
   • False

   Hint

   Think about when jumps occur.

5. 5.

   Design a finite state machine for executing a conditional jump instruction, ensuring to include various states and control signals relevant to flag usage.

   Hint

   Map out flows and decisions based on flag values during state transitions.

6. 6.

   Critique the implications of having an FSM tailored for each opcode versus a more consolidated FSM for multiple similar instructions.

   Hint

   Consider speed versus space in the context of computer architecture.
