...and other technology commodities chips designers have gotten used to the idea that businesses are willing to hand over large amounts of money to use their kit. It seems to me that if a company really wanted to shake up a market they would do a lot more to lower the barriers of entry into that market. "Open Source" CPU designs might let companies with big budgets take their business in a new direction. However I have not seen a single product from a start up or boutique shop using them. I have read about ideas and heard investment pitches but I have not seen any real world products.
Don't misunderstand me though, I think that anything the industry does to make technology more accessible is in the best interest of the business and humanity. So I see this as a step in the right direction. I know they need to make money off of the IP they have created.
On the other hand, if this isn't last stop on the Moore's Law Bus then you can at least see it from here. I predict that the "Open Source" CPU company that has the lowest cost to market for small businesses and start ups over the next 5 years will be the company we read the most news about the following 10 years.
