7.2.3. Types of Instructions

Try these first

1. 1.

   What is a macro instruction?

   Hint

   Think about the complexity of instructions.

2. 2.

   What is the main function of micro instructions?

   Hint

   Refer to their execution time.

3. 3.

   What do macro instructions require?

   • One clock cycle
   • Two clock cycles
   • Multiple clock cycles

   Hint

   Think about the complexity of these instructions.

4. 4.

   True or False: Micro instructions can execute multiple steps in one clock cycle.

   • True
   • False

   Hint

   Consider the definition of micro instructions.

5. 5.

   Given a series of macro instructions, analyze and design the corresponding micro instructions required to execute them efficiently in a hypothetical CPU.

   Hint

   Consider each instruction’s complexity and dependencies.

6. 6.

   Propose a scenario in which clock grouping might save time in instruction execution. Illustrate with examples.

   Hint

   Think about parallel processing capabilities.
