# metadata.contentDescription
This document is the Architecture Specification for the MPAM Extension Architecture Specification v1.0, and v1.1. It also describes MPAM for RME, that is, the additions made to support features introduced by the Realm Management Extension (RME), and the MPAM 2021 Extensions. This document is now RETIRED. The Arm Architecture Reference Manual for A-profile architecture (DDI0487) is the definitive reference for the CPU architecture specification. The Memory System Resource Partitioning and Monitoring (MPAM) System Component Specification (IHI0099) is the definitive reference for the System Component specification.
