5.2.2. Context Saving During Procedure Call

Try these first

1. 1.

   What does the stack pointer do?

   Hint

   Think about where data is stored during function calls.

2. 2.

   What happens during a push operation?

   Hint

   Consider how the stack grows.

3. 3.

   What is the role of the stack pointer?

   • It holds the program counter
   • It tracks the top of the stack
   • It executes instructions

   Hint

   Think about what keeps track of the data location.

4. 4.

   True or False: A return operation pops the last context off the stack.

   • True
   • False

   Hint

   Consider how procedures return to previous calls.

5. 5.

   Explain how context saving impacts performance during a series of rapid procedure calls.

   Hint

   Think about how frequently the context might need modification during many calls.

6. 6.

   Design a flowchart that illustrates the push and pop processes in the context of procedure calls.

   Hint

   Visualize the process, including inputs to the stack and outputs after popping.
