7.2. First Unit: Macro Instructions

Try these first

1. 1.

   What is the purpose of macro instructions?

   Hint

   Think about how a recipe outlines steps for a dish.

2. 2.

   Define a micro instruction.

   Hint

   Consider it like a single step in a larger process.

3. 3.

   What is the difference between macro instructions and micro instructions?

   • Macro instructions are simpler and faster.
   • Micro instructions can be executed in a single clock cycle.
   • Macro instructions execute in one clock cycle.

   Hint

   Focus on execution time and complexity.

4. 4.

   True or False: All instructions execute in the same amount of time.

   • True
   • False

   Hint

   Think about the differences in instruction types.

5. 5.

   Design a simple instruction cycle for an instruction that requires both a fetch and an execute without an intermediate storage phase.

   Hint

   Think about how to streamline the process.

6. 6.

   Analyze how changing the processing speed affects the execution of complex macro instructions.

   Hint

   Consider the relationship between clock speed and execution time.
