20.5.3. Control Signals in Micro-programmed Control

Try these first

1. 1.

   What are control signals in a micro-programmed control unit?

   Hint

   Think about the roles of commands within a computer.

2. 2.

   How does a micro-programmed control unit differ from a hardwired control unit?

   Hint

   Consider flexibility versus speed.

3. 3.

   What does a micro-programmed control unit use to generate control signals?

   • A set of fixed circuits
   • Programs stored in memory
   • Random logic gates

   Hint

   Focus on what enables changes and flexibility.

4. 4.

   True or False: Hardwired control units are more flexible than micro-programmed control units.

   • True
   • False

   Hint

   Remember the definitions of both types.

5. 5.

   Create a micro-program control sequence for adding two numbers stored in memory. Explain each step.

   Hint

   Break down the addition process into incremental steps.

6. 6.

   Explain how a conditional jump would be processed in micro-program control. What fundamental differences does this introduce compared to a hardwired system?

   Hint

   Think about how decisions are made in both scenarios.
