7.4. Optimization Techniques

Try these first

1. 1.

   What is a macro instruction?

   Hint

   Think about the complexity of tasks.

2. 2.

   Define a micro instruction.

   Hint

   Consider what happens in a single clock cycle.

3. 3.

   What is a macro instruction?

   • A simple operation
   • An atomic instruction
   • A complex instruction

   Hint

   Consider how many steps are included.

4. 4.

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

   • True
   • False

   Hint

   Think about what makes them 'micro.'

5. 5.

   Given a complex instruction involving multiple registers, propose a strategy to optimize its execution using clock grouping.

   Hint

   Evaluate the relationship between each micro instruction.

6. 6.

   Develop a flowchart illustrating the phases and micro instructions for a sample ADD instruction involving indirect addressing.

   Hint

   Break down each step systematically in your flowchart.
