In this assignment, you will create a program in C to simulate the instruction life cycle of a simplified

computer architecture. You will implement a fetch$-$decode$-$execute cycle and demonstrate how different

op codes affect the execution of instructions. $(10$ Marks$)$

Scenario Description:

Imagine you are a computer architect tasked with building a simulator for a basic computer architecture.

Your goal is to create a program that can execute a series of instructions, each with its own op code, and

show how the fetch$-$decode$-$execute cycle works.

Requirements:

$1.$ Write a C program named instruction$\_$simulator.c$.$

$2.$ Define a simplified instruction set with at least five different op codes. Each op code should

correspond to a specific operation $($e$.$g$.,$ ADD, SUB, LOAD, STORE, etc.$).$ Create an enum or

constants to represent these op codes.

$3.$ Implement a fetch$-$decode$-$execute cycle within a loop that processes a sequence of instructions.

The cycle should include the following steps:

a$.$ Fetch: Fetch the next instruction from memory.

b$.$ Decode: Determine the operation to be performed based on the op code.

c$.$ Execute: Perform the operation and update the program state accordingly.

$4.$ Create a data structure $($e$.$g$.,$ an array$)$ to represent the memory of the computer. Initialize this

memory with a sequence of instructions using the op codes defined in step $2.$

$5.$ Print the state of the computer $($e$.$g$.,$ memory contents, registers$)$ before and after each

instruction is executed.

$6.$ Implement at least two sample programs using your defined op codes and memory layout.

$7.$ These programs should consist of sequences of instructions that demonstrate various operations

and interactions between instructions.

$8.$ Use comments to explain the purpose of each part of your code and how the fetch$-$decodeexecute cycle works.
