Helping our partners to master technologies
We offer first-hand experience as Free Software developers, bringing companies to full speed by exploiting GNU/Linux in real-life environments.
Offering everyone freedom of choice
Free Software means freedom to change and port to different environments. Thus, we don't bind anyone to a specific hardware platform or software environment; you can build on what we give you, to better serve your business needs. By delivering all the information associated to our software or services, we enpower our partners without making them dependent on us.
Respecting and leveraging copyright and droit d'auteur
Our long-standing experience with the best Free Software packages enables us to pick the most suitable technologies and include or adapt them to the problems we face. Thus, the copyright holders of our packages are the developers themselves - this way, the positive feedback associated to code sharing is fostered. In order to best serve our clients' privacy concerns and to obey their copyright terms, we won't get directly involved in proprietary code and we'll focus on the Free Software system components.
Delivering top-quality solutions
Our software packages and our working documents guarantee high quality because we build them on the basis of state-of-the-art information and resources, and design them to withstand public review.
Linux device driver and associated utilities for PCIe FMC carriers.
The FMC bus abstraction implements a Linux kernel bus named fmc. This
allows to deal with FMC mezzanines in a carrier-independent way
This project covers all efforts geared to standardize White Rabbit, with
a view to providing a stable specification which everyone can use to
build compliant products.
Software support for the SVEC board, including kernel and user-space
Software support for the SPEC board, including kernel and user-space
The package also include the fmc-bus driver, which is expected to be
used by other carriers as well.
Development of software for the White Rabbit switch, and in particular
the embedded Linux system running in the ARM9 processor.

A software framework for Linux device drivers aimed at supporting
controls and data acquisition hardware.
ZIO supports sub-nanosecond timestamps, block-oriented input and output
and transport of meta-data with the data samples. Users can change the
buffer type and trigger type associated with a device at run time, and
all of devices, triggers and buffers are easily implemented as add-on
The PF_ZIO implementation, currently in beta status, implements a
network interface to the ZIO transport, which allows each I/O channel to
generate or receive network frames. Applications see the network of
devices and can talk with several of them from the same socket. We
support SOCK_STREAM, SOCK_DGRAM and SOCK_RAW.
A simple 4-lane PCIe carrier for a low pin count FPGA Mezzanine Card
(VITA 57). It supports the White Rabbit timing and control network.
Commercially available. Linux and Labview drivers available for some

GTS is a tool which takes a binary for a given microprocessor (initially
an LM32) and gives information about worst-case execution time.
A Precise Time Protocol (PTP, IEEE 1588) software stack whose single
source code can be compiled for many architectures (POSIX systems, WR
switch, WR node, ...) and which is easily extensible.
This project defines data structures, to be embedded in the FPGA memory
address space, to enumerate the devices that have been synthetized in
the current design. The same structure is also used as a simple flash
file system. AKA Self-Describing Bus (SDB) Specification for Logic
Cores. The layout is simple enough to be parsed both by the host and by
the internal soft-core, if any.
The documentation is public, and related code is GNU GPL licensed.
White Rabbit PTP Core software for LatticeMico32. It consists of a
software wrapper for running a PTP daemon without an operating system
and device drivers for WRPC HDL internals.
Software to support the fmc-adc-100m14b4cha mezzanine, including Linux
device driver, library and test program.
This is a port of an older Linux ptpd to support White Rabbit extensions
and run both in hosted and freestanding environment. In the future we
plan to replace it with PPSI, which has a much better design, but
ptp-noposix is currently working pretty well despite being difficult to
A White Rabbit compliant Network Interface Card (NIC) based on the
SPEC and the DIO
FMC. This project
hosts the HDL and associated software to configure the SPEC so it
behaves as a NIC under the Linux OS.
Host-side software support for the fine delay FMC on the SPEC and SVEC
More details in the project
White Rabbit is a fully deterministic Ethernet-based network for general
purpose data transfer and synchronization. It can synchronize over 1000
nodes with sub-ns accuracy over fiber lengths of up to 10 km.

A project to host all software and hardware developments related to
testing the White Rabbit switch.
