BERI Open Systems C.I.C.

BERI Open Systems is a not-for-profit UK Community Interest Company (C.I.C.) supporting the community of academic, educational, industrial, and hobbyist users of the open-source hardware-software designs such as the BERI processor. BERI Open Systems will act as a holder and licenser of open-source hardware-software designs, with a particular interest in research and teaching applications.

Bluespec Extensible RISC Implementation (BERI)
The BERI processor is a Bluespec-based design for a pipelined 64-bit RISC processor suitable for research and teaching developed at SRI International and the University of Cambridge.

BERI license and agreements

The BERI open-source hardware-software license extends the Apache Software License with additional intellectual property types specific to hardware designs – e.g., mask rights – in order to better support open-source hardware. It is our hope that organisations such as Apache may accept open-source hardware as part of their remit in the future, both in terms of licenses and willingness to host open-source hardware projects, in which case working with an extended license might cease to be necessary.

The BERI open-source hardware-software license agreement is derived from the Apache Software Foundation's Apache Software License 2.0, with minor modifications extending it to support additional intellectual property rights associated with hardware (e.g., mask rights). We have prepared a diff between the two open-source licenses for interested parties to inspect. The Apache Software Foundation guidance on documenting copyright and license in source files applies and will be used for all BERI projects.
