19.3.2. Micro Program Based Control

Try these first

1. 1.

   Define what a micro instruction is.

   Hint

   Think about the detailed steps involved in executing an instruction.

2. 2.

   What is the role of the program counter?

   Hint

   Consider its importance in the instruction cycle.

3. 3.

   What does the program counter (PC) do?

   • Stores data
   • Tracks the next instruction
   • Resets memory

   Hint

   Consider its role in the sequence of instructions.

4. 4.

   True or False: Control signals are irrelevant to efficient instruction execution.

   • True
   • False

   Hint

   Think about how operations are initiated and managed.

5. 5.

   Design a simple state diagram for the ADD instruction highlighting key states and transitions.

   Hint

   Visualize the journey of an instruction from start to finish.

6. 6.

   Analyze how the addition of a new instruction affects the existing finite state machine design.

   Hint

   Examine the sequence of operations that might change.
