OpenRISC was conceived in 1999 as a project to specify a RISC
processor architecture and hardware implementations that were entirely
open source.

The OpenRISC 1200 was the first implementation of that architecture.
It has been in use for around a decade and is powerful enough to run
Linux. Now on its third revision, the processor is widely used in
research projects, and has also been used in a number of commercial

The project has spawned a host of peripheral hardware components, so
that several complete systems-on-chip are now available. All are open
source and hosted on

Any modern chip relies heavily on software. Tools to design the chip,
software tool chains for programs to run on the chip and operating
system infrastructure. For OpenRISC, nearly all that has also been
achieved using open source software.

This talk will introduce the OpenRISC 1000 project, focussing
particularly on the role of open source software. Involving hardware
leads to some interesting open source licensing problems, which will be
addressed in the presentation.

The final part of the talk will be a practical demonstration of
OpenRISC in action, using both hardware and the architectural simulator.
All the software will be available on DVD and attendees with Linux
laptops are invited to join in the practical part.
