Not everyone working on CPU architecture is with one of the big manufacturers.
In part 3, Ivan talks a little bit about the structure of the company. At this point, it is a completely self-funded "company of incorporators," a common place to be, where there are contractual agreements on how things will be divided eventually. They have been working on this for 10 years, which means that the team has changed many times over the years.
When asked how close they are to producing something, Godard offers his best estimate at roughly one year to 18 months. He elaborates that it could be two to three years before they have "saleable silicon," but again this is all an extremely rough estimate.
If you're wondering why others haven't done all this already, Godard has some thoughts for you. He explains his theories as to why others haven't explored this method, pointing out that others do in fact make changes, but those tend to be fairly small improvements on existing items.
This interview was quite enlightening. The Mill seems like something we'll be hearing a lot more about in the coming years. I'm very curious to see how much of the expected power efficiencies actually carry over from simulation to the physical product. I'll be keeping my eye on these folks for sure.
