Question 1.
Define a microprogram.
Show hintHide hint
Think of it as the 'sub-instructions' for the main instruction.
Question 2.
What is the purpose of branching in microprograms?
Show hintHide hint
Consider how similar tasks might use the same instructions.
3Question 3.
What does a microprogram control memory store?
- Microinstructions
- Macro instructions
- Control signals
Show hintHide hint
What is contained in the memory that's used to manage instruction execution?
4Question 4.
True or false: Branching is unnecessary for optimizing microprograms.
- True
- False
Show hintHide hint
Think about whether you want to copy large sections of code for similar tasks.
Question 5.
Design a microprogram that optimally uses branching to execute four different arithmetic operations.
Show hintHide hint
Consider what shared steps each operation might have.
Question 6.
Evaluate and suggest improvements for a given microprogram that currently performs poorly due to high memory usage.
Show hintHide hint
Look for repeated patterns that you could consolidate.
