15.1.2. Instruction Load

Try these first

1. 1.

   What does indirect addressing mean?

   Hint

   Think about how a contact list leads to a specific person.

2. 2.

   What does the Program Counter do?

   Hint

   Remember, it’s like a queue for the tasks.

3. 3.

   What is the primary function of the Program Counter?

   • To execute instructions
   • To hold the address of the next instruction
   • To store data temporarily

   Hint

   What helps in organizing task execution?

4. 4.

   True or False: The indirect addressing mode requires fewer operations than the register indirect mode.

   • True
   • False

   Hint

   Recall the number of stages discussed.

5. 5.

   You need to load a series of instructions where the first one uses indirect addressing, then register indirect addressing. Describe the combined control steps.

   Hint

   Combine and outline the flow for both modes.

6. 6.

   Draw a flow chart representing the control steps for indirect addressing, indicating where delays may occur.

   Hint

   Visualize the steps like a flow diagram.
