The Free and Open Source Silicon Foundation (FOSSi Foundation) is a non-profit foundation with the mission to promote and assist free and open digital hardware designs and their related ecosystems. It was set up by the core OpenRISC development team in response to decreasing support from the commercial owners of the opencores.org website. The main sponsor of the FOSSi Foundation is Google and past sponsors included Cadence Design Systems and Embecosm. The FOSSi Foundation should not be confused with the Free Silicon Foundation.
