15.1.3. Value Feeding into Memory Address Register

Try these first

1. 1.

   What is indirect addressing?

   Hint

   Think about how one address can point to another.

2. 2.

   What does the MAR do?

   Hint

   Recall what happens when fetching instructions.

3. 3.

   What is the primary function of the Memory Address Register?

   • To hold data
   • To hold addresses
   • To perform arithmetic operations

   Hint

   Remember the role it plays in fetching instructions.

4. 4.

   True or False: Indirect addressing mode requires multiple memory accesses.

   • True
   • False

   Hint

   Consider how indirect addressing works.

5. 5.

   Design a flowchart detailing the step-by-step process for fetching an operand using indirect addressing. Include all necessary stages.

   Hint

   Sketch out the workflow and see each stage as a separate box.

6. 6.

   Create a programming snippet demonstrating the use of indirect addressing in a dynamic array context.

   Hint

   Develop a mini-program that simulates fetching values dynamically.
