OpenRISC is an Open Source CPU that brings to the world of hardware all the same advantages that Open Source software has known for so long. The OpenRISC project is community-driven with most of the action on IRC at Freenode (#openrisc) and on our mailing lists.

These pages primarily target the Linux on OpenRISC use-case and aim to help you get up to speed as quickly as possible. Feedback on these pages and questions not answered here should be directed to the mailing list or vented on #openrisc at freenode. We look forward to your becoming a part of the larger OpenRISC family!
