Generates a Fused Multiply Add (FMA) unit in Verilog.

pip install pyrilog

NOTE: Currently not on PyPi yet - therefore the pip command would not work.

Alternatively, you can clone this repository and run:

python -m pyrilog <...args>

The Fused Multiply Add operation is in the form:

a + b * c

However, in our case, we are not taking a as the accumulated value, but we will keep a as an expanded value of the partial products so that we can perform the operation of a matrix dot product in a parallel fashion.

pyrilog --size <size> --width <width> --with-pipeline

• --size: size of the vectors that we want to perform dot product on
• --width: bit width of each element in the vectors that we want to perform dot product on
• --with-pipeline: we'll include latches in between the stages of the reduction tree if this is enabled (work in progress)

It is recommended that you test and verify the generated Verilog code using a test bench with Icarus Verilog before deploying to any hardware. Pyrilog does not provide generated Verilog code to run as a test bench, although that would be pretty awesome.

Work-in-Progress. I'm hoping to use the GitHub wiki as the main source of documentation.

If you are interested to contribute, feel free to take a look at the issues. Feel free to clone this repository and make pull requests if you think there are improvements to be made.

Clone the repository, create a virtualenv and run:

pip install -r requirements.txt

Please remember to run tests before submitting a PR:

nosetests ./tests/**/*.py --with-coverage

Pyrilog is developed in a Python 3.6.2 environment, however there should be support for lower versions of Python 3. I cannot guarantee support for Python 2 versions.
