Stack Operations Illustration, PUSH and POP

Since the diagram in our Module doesn’t seem to be too clear on how it works, so here’s a better diagram.

• Program Counter (PC) has to move downward in both cases (PUSH or POP), since it will need to move to the next code.
• Stack Pointer (SP) moves up in PUSH, while it moves down in POP.

Please do not hesitate to correct me if I’m wrong.
