Writing a very basic CPU in Verilog

This is an experimental exercices for writing different CPUs in Verilog and Python

Project Overview

This repository contains various implementations of CPUs

If you're interested in looking around, I would recommend you to start with two_bit_computer. Since it a very basic version, which comes with all the necessary command you need to playaround with it.

Checkout the example_boilerplate_code_for_getting_started folder to know how the project has been setup for writing and running Verilog programs

There are 3 basic versions of the CPU which you can look into if you'r ea beginner or you want to know how a CPU works. All of the code are written basic Verilog. So it would be easy to understand.

Checkout:

• version_2
• version_3
• version_4

Things you need to run the programs

• Icarus Verilog
• Python

Checkout the Makefile in project directories to know more about the command to run

Assembler code

For two_bit_computer and three_bit_computer, we have a custom Assembler written in python. You can write your assembly instructions in instructions.txt file and use the commands mentioned in the Makefile to assemble and run the programs on the CPU.
