Question 1.
Define an explicit jump.
Show hintHide hint
Think about when you must directly specify where to go next.
Question 2.
What does the zero flag indicate?
Show hintHide hint
Consider how you might respond if a calculation turns out to be zero.
3Question 3.
What is an explicit jump?
- A jump that occurs automatically
- A conditional transfer dictated by flags
- A repeat command
Show hintHide hint
Think about when control must be specified directly.
4Question 4.
The zero flag indicates the last computation resulted in which of the following?
- True
- False
Show hintHide hint
What happens when you find a calculation that equals zero?
Question 5.
Construct a flowchart illustrating the decision process of executing an explicit jump versus an implicit jump in a microprogram.
Show hintHide hint
Outline each decision point clearly, picturing the program's flow.
Question 6.
Propose an alternative implementation of a microprogram that combines multiple instructions into a single routine while maintaining clarity. Discuss the efficiency gained versus complexity introduced.
Show hintHide hint
Analyze the balance between complexity and advantage.
