Dahlia

Dahlia is an imperative, loop-based programming language for designing hardware accelerators.

Installation

First, install sbt and scala.

Then, clone the repository and build the Dahlia compiler:

git clone https://github.com/cucapra/dahlia.git
cd dahlia
sbt compile
sbt assembly
chmod +x ./fuse

The Dahlia compiler can be run using the ./fuse binary:

./fuse --help

Finally, configure fud2 to use the Dahlia compiler. Type fud2 edit-config and add a line like this:

dahlia = "<path to Dahlia repository>/fuse"

If something went wrong, try following the instructions to build the Dahlia compiler from its repository.

Dahlia programs can be compiled to Calyx using:

fud2 --from dahlia <input file> --to calyx

The Dahlia backend for Calyx is neither complete nor stable. If you find a confusing error or wrong program, please open an issue.
