22.2.1. Load and Increment

Try these first

1. 1.

   What is the role of the micro-program counter (MPC)?

   Hint

   It's crucial for determining instruction flow.

2. 2.

   What is the purpose of control signals?

   Hint

   Think about what happens to the instruction sequence.

3. 3.

   What does the micro-program counter (MPC) do?

   • a) Holds data values
   • b) Determines address for next micro-instruction
   • c) Sets control flags

   Hint

   Consider its fundamental purpose in the control unit.

4. 4.

   True or False: Conditional jumps only occur if specific conditions are met.

   • True
   • False

   Hint

   Remember what dictates the instruction flow.

5. 5.

   Create a scenario where a micro-program counter must decide between a conditional jump and an increment based on a sequence of operations and explain your reasoning.

   Hint

   Think about how inputs could change the flow.

6. 6.

   In a given micro-program, devise a strategy for managing sparse control signals effectively within the micro-program control memory.

   Hint

   Explore alternatives that optimize memory usage.
