❄️ Overview

ColdCPU is a custom-made fictional processor architecture and assembly language written in C++. It offers a comprehensive toolchain for compiling, cross-platform emulation, and disassembly.

🚀 Features

• Turing Completeness: Supports arithmetic, floating-point and bitwise operations.
• Control Flow: Conditional branching for complex program logic.
• Memory Operations: Secure memory model with fast load/store instructions.
• Clean & Simple: ColdCPU provides an educational reference designed to explore low-level architecture concepts and enhance understanding of basic processor functionality.
• Examples: Several examples of programs written in the cold assembly language have been provided in the workdir folder of this repository.

📚 Usage

Assembler

Usage: coldasm --input PATH --output PATH

Emulator

Usage: coldemu --path PATH [--memory VAR]

Optional arguments:
  -m, --memory   memory size in bytes [default: 1024]

Disassembler

Usage: colddsm --input PATH --output PATH

See the documentation for more detailed information about the processor and toolchain in the wiki.

🔨 Building

This project is built upon the Premake5 metabuild system, meaning that it can compile using native build systems depending on the host. Currently, Windows and Linux are supported, and build systems for Visual Studio and GNU Make can be generated for each respectively by running the corresponding setup script found in the scripts directory at the root of the repository.

Steps

• Clone the repository:

git clone https://github.com/cwielder/coldcpu.git
cd coldcpu

• Generate build files:
  • Windows (Visual Studio):

    "./scripts/setupVS.bat"
    

    Open the resulting coldcpu.sln file in Visual Studio 2022+
  • Linux (GNU Make):

    "./scripts/setupMake"
    make
