well, no surprise here, it's this way since 1998 :-D

That's why I start F-GPU :-)
I should write a draft...

The trick is : it will look like what is needed in each specific case.
There will be no "one true" F-CPU SoC, but adaptations of a generic 
model...

So more or less it's about creating a catalogue of blocks and units
that work along/with the CPU. Users will pick the ones they need...
Users would even want to chose the units and configure them
with an interactive graphic tool, no ? :-)

I agree. The tools are critical.
in F-CPU, the tools are not just critical, but they must also be free.

I agree, so let's move on to the F-GPU implementation.
