A Compiler Infrastructure for Accelerator Generators

Calyx is an intermediate language and infrastructure for building compilers that generate custom hardware accelerators. See the [Calyx website][site], [language documentation][docs] and the [documentation for the source code][source-docs] for more information. Calyx's design is based on [our paper][paper]. ## Installation ### Quick If you want to try out the compiler, install it using `cargo`: ``` cargo install futil ``` This will install the `futil` binary which includes the calyx frontend, optimization passes, and several backends. ### Recommended Follow the [getting started][docs] instructions. ## Organization This repository contains the source code for the following: 1. [`calyx`][] (`calyx/`): The intermediate representation used for hardware accelerator generation. 2. [`futil`][] (`src/`): The compiler infrastructure for compiling Calyx programs. If `calyx` is like LLVM, then `futil` is Clang. 3. Calyx debugger (`interp/`): An interpreter and debugger for Calyx. 4. `fud`, The Calyx driver: Utility tool that wraps various hardware toolchains.
