Implement Stack Structure and Fix $sp Register in Project I

[mehmetakifkoz]

Problem:
Project I lacks the stack structure that is essential in MIPS architecture, and the stack pointer register ($sp) is not functioning correctly. These issues prevent accurate simulation of the stack-related operations.

Action Needed:
To rectify this, it's important to integrate the necessary stack structure and ensure the proper functionality of the $sp register.

Steps to Resolve:

1. Introduce the stack structure within the simulation, adhering to the MIPS architecture's stack guidelines.
2. Update the initial value of the stack pointer ($sp) to 0x7fffeffc in the background registers, ensuring it points to the reserved stack memory.

By making these adjustments, the project will be able to precisely emulate stack-related actions, improving the overall accuracy of the MIPS architecture representation.
