Compiler Infrastructure for Accelerator Generators\u003c/a\u003e\n\u003c/p\u003e\n\u003c/h1\u003e\n\nCalyx is an intermediate language and infrastructure for building compilers that generate custom hardware accelerators.\n\nSee the [Calyx website][site], [language documentation][docs] and the [documentation for the source code][source-docs] for more information.\nCalyx's design is based on [our ASPLOS '21 paper][paper].\n\n## Installation\n\n### Quick\nIf you want to try out the compiler, install the [crate][] using `cargo`:\n```\ncargo install calyx\n```\n\nThis will install the `calyx` binary, which can optimize and compile Calyx programs to Verilog or [CIRCT][].\n\n### Recommended\n\nFollow the [getting started][docs] instructions.\n\n## Organization\n\nThis repository contains the source code for the following:\n* [`calyx-utils`][]: Utilities for the Calyx compiler\n* [`calyx-frontend`][]: Parser and frontend AST for the Calyx language.\n* [`calyx-ir`][]: The Calyx intermediate language.\n* [`calyx-opt`][]: Optimizations for the Calyx intermediate language.\n* [`calyx`][]: The Calyx compiler driver.\n\nYou can also use the Calyx compiler as a library and implement your own optimizations. To do this, [check out the example][opt-example] provided by the [`calyx-opt`][] crate.\n\n[site]: https://calyxir.org\n[docs]: https://docs.calyxir.org\n[source-docs]: https://docs.rs/releases/search?query=calyx\n[paper]: https://rachitnigam.com/files/pubs/calyx.pdf\n\n[`calyx-utils`]: https://crates.io/crates/calyx-utils\n[`calyx-frontend`]: https://crates.io/crates/calyx-frontend\n[`calyx-ir`]: https://crates.io/crates/calyx-ir\n[`calyx-opt`]: https://crates.io/crates/calyx-opt\n[`calyx`]: https://crates.io/crates/calyx\n[circt]: https://docs.calyxir.org/running-calyx/fud/circt.html\n[opt-example]: https://docs.rs/calyx-opt/0.2.1/calyx_opt/\n[crate]: https://crates.io/crates/calyx\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcalyxir%2Fcalyx","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcalyxir%2Fcalyx","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcalyxir%2Fcalyx/lists"}
