What is a micro instruction?
Show hintHide hint
Think about the basic building blocks of CPU instructions.
Question 2.
Define an explicit jump.
Show hintHide hint
Consider instructions that are clearly defined in a program.
3Question 3.
What defines an implicit jump?
- It is part of the macro instruction.
- It occurs without direct instruction.
- It is always a conditional jump.
Show hintHide hint
Think about programmability and efficiency similarities.
4Question 4.
True or False: Control signals determine which part of the micro program should execute next.
- True
- False
Show hintHide hint
Consider how instructions are processed in sequence.
Question 5.
You are designing a micro program that has both 'jump on zero' and 'jump on carry' instructions. How would you optimize them for efficiency in your shared micro routine?
Show hintHide hint
Consider how shared processes can reduce redundancy.
Question 6.
Explain what might happen if the control signals are incorrectly set, leading to unintended jumps in a program.
Show hintHide hint
Think about the importance of accuracy in control signal setups.
