# OpenPOWER
In the late 1980s [[!wikipedia IBM]] developed a POWER family of processors.
-This evolved to a specification known as the Power ISA. In 2019 IBM made the Power ISA [[!wikipedia Open_source]] to be looked after by the existing [[!wikipedia OpenPOWER_Foundation]]. Here is a longer history of [[!wikipedia IBM_POWER_microprocessors]].

+happen to implement what is now known as the OpenPOWER ISA. The names
+POWER8, POWER9, POWER10 etc. are product designations equivalent to Intel
+i5, i7, i9 etc. and are frequently conflated with versions of the OpenPOWER ISA (v2.08, v3.0, v3.1).
-Libre-SOC is basing its [[Simple-V Vectorisation|sv]] CPU extensions on OpenPOWER because it wants to be able to specify a machine that can be completely trusted, and because OpenPOWER is designed for high performance.

+is designed for high performance.
