RIFFA
#######################################
`RIFFA <https://github.com/KastnerRG/riffa>`__ is an open-source FPGA core and
kernel driver that abstracts PCIe communication and allows easy integration
into C/C++ programs. We maintain a `fork of the RIFFA driver
<https://github.com/open-ephys/liboni/tree/main/drivers/riffa>`__. RIFFA is
currently the PCIe backend used by Open Ephys.

.. note:: Currently, only 64-bit architectures are supported by RIFFA.
