Understanding Register Stack Organization

In a register stack organization, the stack pointer indicates the current top of the stack. When a PUSH operation is performed, this generally involves adding a new value to the top of the stack.

PUSH Operation Effect on Stack Pointer

1. Behavior of Stack Pointer: In the register stack, when an item is pushed onto the stack, the stack pointer will be adjusted accordingly to reflect that the stack size has increased by one.
2. Stack Growth Direction: Typically, stacks can grow towards lower memory addresses or higher memory addresses. However, in most conventional cases, stacks grow downwards (i.e., the stack pointer is decremented).

Answering the Question

Given the nature of stack operations:

• Stack Pointer Decrement: When the PUSH operation is executed, the stack pointer is usually decremented by the size of the data type being pushed onto the stack, thus reflecting the new top of the stack after the operation.

Final Answer

• Decremented by 1
