finn-plus-driver
Runtime driver for FPGA accelerators generated by finn-plus and deployed to ZYNQ/PYNQ boards.
This package contains everything needed to run a FINN-generated accelerator and nothing
of the compiler itself. It is installed on the board, while the accelerator-specific
artifacts (bitfile, settings.json, runtime weights) are produced by the finn-plus build
flow and copied to the board separately.
Installation
On a PYNQ board, inside the PYNQ virtual environment:
sudo pip install finn-plus-driver
pynq itself is not declared as a dependency: it is part of the board image.
To install the version matching a repository checkout (e.g. in CI):
sudo pip install ./driver
Usage
The driver is usually invoked through its CLI, which instantiates the driver class named in
settings.json and calls one of its member functions:
finn-plus-driver -b bitfile/finn-accel.bit -s driver/settings.json -f throughput_test
It can equally be used as a library:
from finn_plus_driver import FINNDMAOverlay
accel = FINNDMAOverlay("finn-accel.bit", io_shape_dict=io_shape_dict)
output = accel.execute(input_array)
