21.1.4. Incrementing the Micro-Program Counter

Try these first

1. 1.

   What does the Micro-Program Counter (MPC) stand for?

   Hint

   Think about how instructions are managed.

2. 2.

   What are control signals used for?

   Hint

   They help in executing the operations on data.

3. 3.

   What is the primary function of the Micro-Program Counter?

   • To store instructions
   • To manage control signals
   • To initialize operations

   Hint

   Focus on what the MPC does during instruction phases.

4. 4.

   True or False: The MPC always increments after executing a micro-instruction.

   • True
   • False

   Hint

   Think about exceptions to the usual flow.

5. 5.

   Consider a situation where multiple micro-instructions exist for a single macro instruction. Analyze how the MPC differentiates and manages such scenarios.

   Hint

   Think about how the MPC handles variations in execution for related instructions.

6. 6.

   If an instruction sequence includes an unconditional jump, diagram the state of the MPC before and after the jump instruction is executed.

   Hint

   Picture the flow of how the MPC transitions between addresses.
