bfvm 🧠

A simple Brainfuck virtual machine written in C++. This is inspired by Thorsten Ball's article here.

Running 🚀

To run and compile the program run the followig in your terminal: If on Windows

clang++.exe main.cc -o bfvm.exe machine.cc compiler.cc -O3

Linux and Mac:

clang++ main.cc -o bfvm machine.cc compiler.cc -O3

# or
g++ main.cc -o bfvm machine.cc compiler.cc -O3

Benchmacking 📈

Using the Mandelbrot program in the mandelbrot file I have the following result after running

Measure-Command -Expression {.\bfvm.exe .\mandelbrot}

on my Intel Core i3 (11th gen) with 16gb of RAM, running Windows 11 btw.

Testing 🧪

The unit tests inside the *_test.cc file can be run with cmake using the following commands in order

# 1.
cmake -S . -B build -Wno-dev

# 2.

cmake --build build

# 3.

cd build && ctest

Well, if you are using Windows btw, just run the run-test.ps1 script directly.

.\run-test.ps1
