Programmable PowerPC-lite Engine (PPE):

PPE locations and usages on POWER9

A reduced PowerPC core design based on a subset of the PPC405. Primarily used to handle power management functions in the form of one CME instance per SMT8 slice (one shared instance per pair of SMT4 cores). Instances of the PPE are also used to implement the SBE, I/O PPE, and PB PPE.
