14.5.2. Direct Mode Example

Try these first

1. 1.

   What is the immediate addressing mode?

   Hint

   Think about how some instructions specify values directly.

2. 2.

   How many steps does direct addressing require?

   Hint

   Recall the comparison made between direct and immediate modes.

3. 3.

   What is an immediate addressing mode?

   • The operand is in the instruction.
   • The operand is at a specific memory address.
   • The operand is at an address specified by another memory location.

   Hint

   Think about where the operand comes from.

4. 4.

   True or False: Direct addressing requires more steps than immediate addressing.

   • True
   • False

   Hint

   Consider how many steps each mode requires.

5. 5.

   Evaluate the scenarios where choosing indirect addressing would be more beneficial than immediate addressing.

   Hint

   Think about situations where data might change frequently.

6. 6.

   Prepare a brief comparative analysis explaining when to use immediate versus direct addressing based on their operational costs.

   Hint

   Consider usage patterns in common algorithms.
