5.2.1. Stack Pointer and Memory Allocation

Try these first

1. 1.

   What does the stack pointer do?

   Hint

   Think about how stacks work.

2. 2.

   What is a procedure call?

   Hint

   Consider what happens when a function is called.

3. 3.

   What operation does a stack pointer perform?

   • Tracks procedure calls
   • Manages processor speed
   • Points to current stack location

   Hint

   Think about its function in memory management.

4. 4.

   True or False: A nested procedure call requires returning to each calling procedure in reverse order.

   • True
   • False

   Hint

   Visualize the stack and how calls overlap.

5. 5.

   Explain in detail how a CPU handles nested procedure calls and the context saving involved.

   Hint

   Think through each step of the call and return process.

6. 6.

   Create a diagram showing memory addresses of a main program and two procedures along with the stack pointer’s position during procedure calls.

   Hint

   Consider how the stack grows and where the procedures lie.
