Question 1.
What is a microprogram?
Show hintHide hint
Think about how it relates to CPU instruction execution.
Question 2.
Define a macroinstruction.
Show hintHide hint
Consider its role in the instruction cycle.
3Question 3.
What is the primary function of the Microprogram Counter (MPC)?
- To store macroinstructions
- To fetch microinstructions
- To decode macroinstructions
Show hintHide hint
Think about how instructions flow through the CPU.
4Question 4.
Branching is used in microprograms primarily for what purpose?
- True
- False
Show hintHide hint
Recall the definition of branching.
Question 5.
Consider a CPU architecture that uses extensive branching but lacks optimization techniques. How might this affect performance and memory usage? Provide detailed analysis.
Show hintHide hint
Think of how redundant paths within execution could slow down processing.
Question 6.
Design a microprogram that executes addition and subtraction using shared sequences where possible. Outline your approach and the resultant sequences.
Show hintHide hint
Map out the shared steps first before diving into specific operations.
