On the first day...
2015-03-27 : I sent a little message to a forgotten mailing list, and it worked.
The historical mailing list at http://archives.seul.org/f-cpu/f-cpu/ is still alive, though it might move someday, once we find a suitable host. This is still where every important discussions take place. The subscribers list has been cleaned up over a week, shrinking by one half from almost 150 initially. And two dozens of people seem to be as eager as before, even though everything has changed in a decade.
The seul.org service at MIT has disabled the team's accounts after a server breach so http://f-cpu.seul.org is stuck... For an undefined time... It will be conserved for posterity, while a new private server is being set up.https://www.facebook.com/FreedomCPU and you'll find more or less the same info as here, digested in a slightly different format.
Unlike earlier, there will not be a french mailing list or geographic sub-groups, to reduce the scattering/dilution of efforts and the duplication of informations. However there will be subgroups dedicated to specific domains or subprojects, such as the hardware platform or compilers...
Ah, the hardware question ! That is something that differs considerably since year 2000.
It is now possible to simulate VHDL code with the now solid GHDL simulator. No more messy cross-platform constraints, and I have developed several handy extensions over the years for maximum development comfort :-)
The implementation side is now much more affordable with FPGA. I use Actel/Microsemi's ProASIC3 family pofessionally for several years, I'll support the new Igloo2/SmartFusion2 chips soon as well for more performance.
Several platforms are suitable to develop the F-CPU HDL code, including Fusion-based or SmartFusion2-based development boards. But we need a real demonstrator, a credible development target. I've realised that the constraints and the purposes fit very well with a design that was evaluated in 2009 : the GPL (Gaming Platform Libre). The difference is that in 6 years, the new generation of Microsemi FPGA solve the problems that were raised. And to help create a SmartFusion2-based system board, long-time F-CPU lurker JG is collaborating. The updated GPL design is now upgraded to the new project: F-GPU (Fun Gaming Platform Unit).
F-GPU is not about designing a GPU, or a game console, but a self-contained and Libre development environment for CPU cores. It reuses most of the work of a cousin project, the YASEP and this small microcontroller will sit next to the F-CPU core to assist with the low-level tasks. The software development tools will also be shared, so a rewrite of the YGWM toolkit has started.
As more tools and methods are ported from the YASEP, expect a boost in features, usability, accessibility and fun in the F-CPU project !
