Power Architecture Platform Reference

From Wikipedia, the free encyclopedia

Power Architecture Platform Reference (PAPR) is an initiative from Power.org to make a new open computing platform based on Power Architecture technology. It follows two previous attempts, PReP and CHRP in the 1990's.

The PAPR specification provides the foundation for development of standard Power Architecture computers running the Linux operating system. PAPR is Power.org's move toward what IBM did originally with CHRP, in that it defines a common hardware definition and software/firmware platform under a set of requirements.

Future versions may include "PAPR-E" and "PAPR-M" specifications for embedded and multimedia applications.[1]

Wind River will lead the Power.org committee that will develop the ePAPR specification.[2]
