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!
If you have any questions, comments, or ideas regarding hls4ml or just want to show us how you use hls4ml, don't hesitate to reach us through the [discussions](https://github.com/fastmachinelearning/hls4ml/discussions) tab.
# Documentation & Tutorial
For more information visit the webpage: [https://fastmachinelearning.org/hls4ml/](https://fastmachinelearning.org/hls4ml/).
For introductory material on FPGAs, HLS and ML inferences using hls4ml, check out the [video](https://www.youtube.com/watch?v=2y3GNY4tf7A&ab_channel=SystemsGroupatETHZ%C3%BCrich).
Detailed tutorials on how to use `hls4ml`'s various functionalities can be found [here](https://github.com/hls-fpga-machine-learning/hls4ml-tutorial).
# Installation
```bash
pip install hls4ml
```
To install the extra dependencies for profiling:
```bash
pip install hls4ml[profiling]
```
# Getting Started
### Creating an HLS project
```Python
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')
# You can print the configuration to see some default parameters
print(config)
# 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.
We will build the project using Xilinx Vivado HLS, which can be downloaded and installed from [here](https://www.xilinx.com/products/design-tools/vivado/integration/esl-design.html). Alongside Vivado HLS, hls4ml also supports Vitis HLS, Intel HLS, Catapult HLS and has some experimental support dor Intel oneAPI. The target back-end can be changed using the argument backend when building the model.
```Python
# 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')
```
