RISC-V comes to mind as an open and free instruction set. The step to an actual implemented-in-silicon processor is pretty big though, and for any such chip it's hard to verify that it really is as free as it's claimed to be. You can't diassemble your CPU (or perhaps you can, but for very few values of "you").
- lallysingh 10y agoYeah, basically you have to have a bunch made and destructively analyze some of them (https://www.extremetech.com/extreme/141077-how-to-crack-open-some-computer-chips-and-take-your-own-die-shots https://www.extremetech.com/extreme/141077-how-to-crack-open...). That'll build confidence that the others aren't compromised. The costs could be reasonable (http://electronics.stackexchange.com/questions/7042/how-much-does-it-cost-to-have-a-custom-asic-made http://electronics.stackexchange.com/questions/7042/how-much...) under a kickstarter-style campaign.
