14.5. Examples of Addressing Modes

Try these first

1. 1.

   What is immediate addressing mode and give an example.

   Hint

   Think of instructions that load values directly.

2. 2.

   How many steps are involved in immediate addressing?

   Hint

   Recall the value associated with immediate addressing.

3. 3.

   What is the main feature of immediate addressing mode?

   • The operand's address is specified
   • The operand is part of the instruction
   • Requires more memory accesses

   Hint

   Think of instructions like `LOAD R1, 10`.

4. 4.

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

   • True
   • False

   Hint

   Visualize the steps involved in indirect addressing.

5. 5.

   Given an instruction that uses direct addressing to store a value, explain the execution process step-by-step.

   Hint

   Outline every step neatly per the control instruction sequence.

6. 6.

   Contrast the efficiency of immediate vs. indirect addressing modes for loading integer values in a CPU.

   Hint

   Consider both access times and the number of accesses required.
