Genode FX executes a full GUI software stack on a soft core CPU implementation (e.g., Microblaze) or on a hard wired CPU (e.g., PPC core as featured by Virtex4 FPGAs). For interfacing input devices and the display to the system, the CPU core is complemented by custom peripheral components.

At the current stage, Genode FX consists of the following components:

• Display controller for VGA and DVI output

• PS/2 controller for mouse and keyboard input

• GUI software stack

• Ready-to-use demonstration projects for Spartan3A Starter Kit boards and Virtex5-based ML507 boards

We develop both the peripheral device components and the GUI software stack in a coordinated fashion. As reference platform, we facilitate the use of the Xilinx Spartan3A Starter Kit with the Microblaze soft core. This cost-effective platform is widely available, for example at Trenz Electronic.

In addition to supporting the Spartan3A Starter Kit, we have implemented Genode FX for other platforms including Virtex4-based FPGA platforms, the ML507, and the Euterpe FPGA board. Furthermore, there exist reference designs for the Trenz Electronic TE0300 + TE0304 FPGA platform, which facilitates the use of industrial FPGA modules for implementing embedded graphics solutions.

Project website and community resources

Before its official release in August 2008, the Genode FX project was conducted by Matthias Alles who was focused on the hardware and Norman Feske who developed the GUI software stack. Since August 2008, the project development is conducted as an open-source community project. The project's resources and the source code are available at the official project website:

project website at Sourceforge

https://sourceforge.net/projects/genode-fx/

The best way for getting involved with the project is joining our mailing lists. The discussion mailing list called Genode-FX-main is the right place for getting in touch with the Genode FPGA graphics developer community, posting propositions for the development, and for requesting help.

The announcements mailing list called Genode-FX-announce is a read-only low-traffic mailing list, which informs you about the progress of the project.
