14.3.3. Immediate Addressing Mode

Try these first

1. 1.

   What does Immediate Addressing Mode involve?

   Hint

   Think about how values are included in instructions.

2. 2.

   How many steps are involved in Immediate Addressing Mode execution?

   Hint

   Compare it to other addressing modes you've learned about.

3. 3.

   In Immediate Addressing Mode, where is the operand specified?

   • In the instruction itself
   • In a separate memory location
   • In an accumulator

   Hint

   Recall what happens when you define an immediate value.

4. 4.

   True or False: Immediate Addressing requires more steps than Direct Addressing.

   • True
   • False

   Hint

   Think about the number of memory accesses involved.

5. 5.

   Create an instruction sequence that utilizes Immediate Addressing Mode to perform arithmetic operations. Include the values used and expected outcomes.

   Hint

   Consider how the immediate value will simplify your calculations.

6. 6.

   Analyze how Immediate Addressing Mode would affect the performance of a program that computes the Fibonacci sequence compared to Direct Addressing.

   Hint

   Think about how many times you would need to access memory in each mode.
