nandputer

A project to implement a nand2tetris-style RISC-V virtual machine in Rust.

Description

The goal of this project is to implement a virtualized RISC-V processor built entirely from NAND (and DFF) components. Rust is used for its speed, memory safety guarantees, and modern programming constructs. This project follows along with the nand2tetris course for chapters 1-3 and 5; RISC-V is implemented instead of the educational Hack architecture.

Getting Started

Dependencies

This project requires a working Cargo installation; if you do not have Rust/Cargo installed, follow the appropriate instructions here.

Installing

git clone https://github.com/witchofthewires/nandputer.git
cd nandputer
cargo build

Executing program

Currently, the project has completed a nand2tetris-style progression up to Level 3: Memory. A full test suite is also implemented, and an interactive testbench is available by executing

cargo run

This opens the nandputer interactive prompt:

nandputer>

Available commands

m - print current outputs of 64-byte memory
w - writes DATA to ADDR, both collected by interactive prompts
q - exit program
