GitHub - 416rehman/computer-from-scratch: A project aimed at building a modern computer bottom-up from scratch

A project aimed at building a modern computer bottom-up from scratch, including the following components:

Hardware Chipset

• Circuitry and Logic Gates for Boolean Arithmetic

• CPU (Central Processing Unit)

• ALU (Arithmetic Logic Unit)

• RAM (Random Access Memory)

Low Level Programming

• Machine Language

• Assembly Language

Virtual Machine

• VM Translator

High-Level Programming

• Object Oriented Programming Language

• Syntax Analysis and Code Generation

• Compiler

• Operating System.

Hardware Chipset

[](#hardware-chipset)

The chipset designed for this computer, including the standard logic-gates, custom ALU, and random-access memory. Logic written and tested using HDL (hardware description language) by Nand2Tetris.

How to use

[](#how-to-use)

Install Nand2Tetris for VS Code

to open the .hdl files, and use the Nand2Tetris's Run Code feature to test the logic for a circuit (tests defined in .tst, and correct results in .cmp)

You can also use the online falstad circuit simulator to run the .circuitjs.txt files to simulate the circuits.

Circuit Designs

[](#circuit-designs)

These are some of the designs implemented using the falstad circuit simulator, the logic for these can be found in the corresponding .circuitjs.txt files.

Arithmetic Logic Unit

Dmux

DMux4way

DMux8Way
