Cosmic

GitHub repo size </br>

Cosmic is a fully simulated computer architecture that provides a full environment to use the Cosmic Processor, specialized devices, ROM, RAM, graphics, and more. The cosmic processor can also be used on a Raspberry Pi to interface with real-world devices. The cosmic system is all entirely accessible in a rich GUI interface that allows for full customization of the system environment and code execution.*

Cosmic is designed to act similar to a real, physical chip but take advantage of it being software-based and leaving some of the nuances of the physical world behind.*

With an instruction set that makes sense (and is fun), and simple memory-mapped I/O, Cosmic is an excellent “chip” to write for, using the cosmic assembler.*

What is Cosmic?

A great educational tool to teach how processors work and assembly language
A very interesting project
A Proof of Concept
Kinda cool
Fun to play with

Cosmic is the Senior Project for Clay Buxton (@clbx) and Kevin Carman (@carmank) at Elizabethtown College. All academically required reports and documentation is in the /doc folder.

Special thanks to @Gwarks, who did a lot of base work on the graphics.

Documentation

Cosmic Processor Specification. This has information about how the processor works, the instruction set, and other general information
Cosmic Assembler Specification. This has information about how to write assembly programs for Cosmic.
Cosmic System Specifications This has information about other parts of the Cosmic system work (Video, Audio, etc.)

Installation Instructions

Be sure to clone recursively, Cosmic uses git submodules

git clone --recursive https://github.com/clbx/Cosmic

If you have already cloned:

git submodule init
git submodule update

Linux

Install SDL2 using your distributions package manager

make

macOS

Install SDL2 using brew. Get brew here if you don’t already have it.

brew install sdl2
make

Windows

A pre-compiled binary can be downloaded from the release page. You will still need to install MinGW and SDL2 Be sure to add both MinGW and SDL2.dll to your path

Compilation Instructions:

Get Chocolatey if you don’t have it already, it helps for installing tools

Install MinGW choco install mingw

Install make choco install make

Download SDL2 Development Library

Untar SDL to the MinGW install directory

make

Make sure any missing .dll’s are in your path

Assembler

The assembler is written in Python, so if you plan on assembling anything for Cosmic, Python 3 is required

/lib contains some included software:

ImGui is a GUI library used for the interface, along with a slightly modified memory editor addon. This is under the MIT License and the license file is included accordingly
ImTui A library that takes ImGui and puts it into a terminal.
gl3w A OpenGL core loader. This is under the unlicense.
catch2 is used for testing. This is under the BSL Software License

SDL2 is also required to run Cosmic.

Cosmic is under the MIT License, feel free to use any part of it, but if you do please include the license file and a link to this repository.
