Speaker: Matteo Michel is there no such thing as open hardware? How does developing future processors with yesterdays capabilities work out today? CPU development is something out of focus these days. In this lecture I would like to show the state-of-the-art processor development flow of POWER processors from the first initial ideas to post-silicon testing. Apart from x86 Intel products there have been initiatives across the hardware industry to form some alternative business model. I would like to show if and how this compares to real open principals.
