Show hintHide hint
Remember the sequence FDES.
3Question 3.
What are micro instructions?
- A. Complex instructions
- B. Simple instructions executed in one clock cycle
- C. Instructions requiring multiple cycles
Show hintHide hint
Consider what 'micro' implies about complexity.
4Question 4.
True or False: All macro instructions can be executed in a single clock cycle.
- True
- False
Show hintHide hint
Reflect on the definition of macro instructions.
Question 5.
Given a macro instruction that involves several arithmetic and logical operations, break down the instruction into its respective micro instructions and identify how many clock cycles would be required to execute each part.
Show hintHide hint
Consider how many steps are involved in each part of your macro instruction.
Question 6.
Design a simple instruction set and for a specific instruction, identify potential micro instructions. Discuss how clock grouping could optimize the instruction's execution.
Show hintHide hint
Look at the operations involved and see which ones can run in parallel.
