21.1. Micro-Programmed Control Unit

Try these first

1. 1.

   What is a micro-programmed control unit tasked with?

   Hint

   Think about the core function of a control unit.

2. 2.

   Define what a micro instruction is.

   Hint

   Consider its relationship to macro instructions.

3. 3.

   What is the primary function of the micro-programmed control unit?

   • To execute instructions
   • To generate control signals
   • To store data

   Hint

   Focus on what the unit is designed to handle.

4. 4.

   True or False: The micro-program counter increments every time an instruction is executed.

   • True
   • False

   Hint

   Think about scenarios that can interrupt the regular incrementing of the MPC.

5. 5.

   Discuss how you would design a micro-programmed control unit capable of handling both conditional and unconditional instructions effectively.

   Hint

   Consider the implications of organization in memory storage.

6. 6.

   Create a table comparing micro instructions and their role in processing macro instructions. Include examples.

   Hint

   Focus on how lower-level instructions facilitate higher-level operations.
