15.2.2. Comparing Indirect Modes

Try these first

1. 1.

   Define indirect addressing mode.

   Hint

   Think about how the operand is retrieved.

2. 2.

   What is the primary difference between memory and register indirect modes?

   Hint

   Consider where the address originates from.

3. 3.

   What does indirect addressing mode imply?

   • A direct memory access
   • Access through another location
   • Immediate value with no address

   Hint

   Focus on the concept of redirection in access.

4. 4.

   In register indirect mode, the address is stored in memory. True or False?

   • True
   • False

   Hint

   Consider where the address is sourced from.

5. 5.

   Explain why register indirect access may lead to better CPU performance in a loop that runs many iterations.

   Hint

   Consider how often memory fetches can slow down performance.

6. 6.

   Design a sequence of operations using mixed addressing modes with a focus on efficiency. Describe your reasoning.

   Hint

   Think about access frequency for the values involved.
