7.6. Micro Instruction Examples

Try these first

1. 1.

   Define a macro instruction.

   Hint

   Think about what a large command in programming would be.

2. 2.

   What does a micro instruction represent?

   Hint

   Consider how complex tasks are broken down.

3. 3.

   What is a macro instruction?

   • A single instruction
   • A high-level operation
   • A type of micro instruction

   Hint

   Think of commands that involve many steps.

4. 4.

   True or False: Micro instructions can execute in multiple clock cycles.

   • True
   • False

   Hint

   Remember the definition of a micro instruction.

5. 5.

   Design a simple computer architecture that includes both macro and micro instructions. Describe at least three macro instructions and their corresponding micro instructions.

   Hint

   Use examples you've learned about macro instructions and think of their micro instructions.

6. 6.

   Evaluate a given instruction: 'SUB R2, R1', and discuss how clock grouping could enhance the execution of this instruction.

   Hint

   Consider which micro instructions can occur at the same time and why they don’t conflict.
