## README

# Deprecation notice
This repo (`finn-base`) is scheduled to be deprecated soon, and should be replaced in any dependent projects with the new QONNX (https://github.com/fastmachinelearning/qonnx) repo. QONNX is nearly a drop-in replacement for `finn-base`, only a namespace change is needed (e.g. `import finn.core.modelwrapper` becomes `import qonnx.core.modelwrapper`).

`finn-base` is part of the [FINN project](https://xilinx.github.io/finn/) and provides the core infrastructure for the [FINN compiler](https://github.com/Xilinx/finn/), including:

* wrapper around ONNX models for easier manipulation
* infrastructure for applying transformation and analysis passes on ONNX graphs
* infrastructure for defining and executing custom ONNX ops (for verification and code generation)
* extensions to ONNX models using annotations, including few-bit data types, sparsity and data layout specifiers
* several transformation passes, including topological sorting, constant folding and convolution lowering
* several custom ops including im2col and multi-thresholding for quantized activations
* several utility functions, including packing for few-bit integers

## Installation

`finn-base` can be installed via pip by [following these instructions](http://finn-base.readthedocs.io/).
