Question 5.
Given a set of instructions using various addressing modes, identify the potential performance bottlenecks.
Show hintHide hint
Focus on how many times memory is accessed versus the speed of retrieval.
Question 6.
Propose an algorithm that optimizes loop performance using displacement addressing and analyze its efficiency.
Show hintHide hint
Consider how adjustment in addresses for each iteration can enhance performance over fixed access.
