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 install
sbt assembly
chmod +x ./fuse

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

./fuse --help

Finally, configure fud to use the Dahlia compiler:

fud c stages.dahlia.exec <path to Dahlia repository>/fuse

Use fud to check if the compiler was installed correctly:

fud check

fud should report that the Dahlia compiler is available and has the right version.

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

Compiling Dahlia to Calyx

Dahlia programs can be compiled to Calyx using:

fud e --from dahlia <input file> --to futil

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