Well that would easily be fixed if someone with the GPL code decided to
share it. The license clearly says you can and that no other restrictions
are allowed to be impossed on the code.
I had never heard of this one before, although looking at their website,
I don't have much hope. I don't think we need another architecture, which
means yet another architecture to support in the kernel, glibc, gcc, not
to mention all the stupid runtimes that need architecture specific code
(hard enough to get those to support existing popular architectures).
And when I see VLIW for a general purpose CPU, I can only think "doomed".
It never worked before, and I don't believe it ever will. But maybe
they don't actually mean VLIW in the traditional sense. Or maybe it is
just intel that can't make it work.
The design looks an awful lot like the tilera tile chips, which are also
lots of cores in a big mesh with lots of fast IO and VLIW. Not sure
they have had much success yet.
Well we will see what happens.
