I sniffed around the site. It smells a bit vapourware-ish. Shipping
CPUs always have pages and pages of silicon bugs. But not the
Tilera. Maybe you get them from behind the secret login page.

Also, compare the level of detail in their brief to one for a real,
shipping product:

   http://focus.ti.com/lit/ug/spru197d/spru197d.pdf

So they're being a bit shy about revealing details, though I did
manage to find a bit more exposed on arse technica:

  http://arstechnica.com/articles/paedia/cpu/MIT-startup-raises-multicore-bar-with-new-64-core-CPU.ars

which makes it sound more credible again. You never know. It does seem
to be a good match for a language with relatively loosely coupled
processes.
