Von-Neumann Architecture Imitation

This repository contains a simple C++ implementation of a Von-Neumann architecture simulator. The program mimics the behavior of a basic computer architecture that uses a single memory space for both instructions and data. Users can load programs, execute them, and view the current state of the memory and registers.

Features

  • Basic Operations: Supports addition, subtraction, multiplication, division, loading from memory, and storing to memory.
  • Instruction Set: Implements a simple instruction set with commands like ADD, SUB, MUL, DIV, LOAD, STORE, and HALT.
  • Memory Initialization: Initializes memory with random values on startup.
  • Interactive Command Line Interface: Users can load programs, run them, and inspect the system's state through an interactive console.

Getting Started

Prerequisites

  • A C++ compiler (like g++, clang++).
  • A basic understanding of C++ and command-line usage.

Compilation

To compile the program, use the following command:

g++ Von-Neumann-ARCH-Imitation.cpp -o von_neumann_simulator

Usage

  1. Run the Simulator:

    Execute the compiled program:

    ./von_neumann_simulator

  2. Commands:

    • LOAD: Input your instructions line by line. Type done to finish inputting.
    • RUN: Execute the loaded program.
    • STATE: Display the current register values and memory state.
    • HELP: Show available commands.
    • QUIT: Exit the simulator.

Example Usage

TICS-OS #> LOAD
ADD 5
SUB 3
MUL 2
DIV 4
done

TICS-OS #> RUN

Implementation Details

  • The simulator initializes a memory space of 1024 integers and supports up to 100 temporary instructions.
  • Registers include Memory Address Register (MAR), Memory Data Register (MDR), Accumulator (AC), and Program Counter (PC).
  • The state of the system is printed after each executed instruction for better visibility.
