A package for machine learning inference in FPGAs. We create firmware implementations of machine learning algorithms using high level synthesis language (HLS). We translate traditional open-source machine learning package models into HLS that can be configured for your use-case!

Detailed tutorials on how to use hls4ml's various functionalities can be found here.
Installation
pip install hls4ml
To install the extra dependencies for profiling:
pip install hls4ml[profiling]
Getting Started
Creating an HLS project
import hls4ml
#Fetch a keras model from our example repository
#This will download our example model to your working directory and return an example configuration file
config = hls4ml.utils.fetch_example_model('KERAS_3layer.json')
print(config) #You can print the configuration to see some default parameters
#Convert it to a hls project
hls_model = hls4ml.converters.keras_to_hls(config)
# Print full list of example models if you want to explore more
hls4ml.utils.fetch_example_list()Building a project with Xilinx Vitis (after downloading and installing from here)
#Use Vivado HLS to synthesize the model
#This might take several minutes
hls_model.build()
#Print out the report if you want
hls4ml.report.read_vivado_report('my-hls-test')
