7.1. Overview of the Module

Try these first

1. 1.

   What is a macro instruction?

   Hint

   Think about what complex operations entail.

2. 2.

   Name the four phases of an instruction cycle.

   Hint

   Recall the acronym F-D-E-S.

3. 3.

   What type of instruction can typically take multiple clock cycles to execute?

   • Micro Instruction
   • Macro Instruction
   • Clock Cycle

   Hint

   Consider the complexity of the instruction.

4. 4.

   True or False: Micro instructions can only be executed in multiple clock cycles.

   • True
   • False

   Hint

   Think about the definition of micro instructions.

5. 5.

   Consider the instruction 'SUB B, A'. Break down this instruction into its potential micro instructions and explain each step.

   Hint

   Think about what each phase of execution requires.

6. 6.

   Given a scenario where two instructions could run concurrently due to non-dependence, illustrate how clock grouping can be applied and its expected outcome.

   Hint

   Consider which instructions can operate independently.
