## Introduction

The **Arm sysarch-acs** repository is a collection of **Architecture Compliance Suites (ACS)** that verify compliance with the following Arm System Architecture specifications:

* **[BSA – Base System Architecture](https://developer.arm.com/documentation/den0094/latest/)**
* **[SBSA – Server Base System Architecture](https://developer.arm.com/documentation/den0029/latest/)**
* **[PC-BSA – Personal Computing Base System Architecture](https://developer.arm.com/documentation/den0151/latest/)**
* **[MPAM (Memory system resource partitioning and monitoring) system component](https://developer.arm.com/documentation/ihi0099/latest/)**
* **[DRTM – Dynamic Root of Trust for Measurement](https://developer.arm.com/documentation/den0113/latest/)**
* **[PFDI – Platform Fault Detection Interface](https://documentation-service.arm.com/static/68593b17961937560be90fbe)**
* **[VBSA – Virtual Base System Architecture](https://developer.arm.com/documentation/den0150/latest/)**

Additionally, it also includes ACS for ...
* **[MemTest](#memory-model-consistency-tests) – Memory Model Consistency tests**

These suites enable silicon vendors, system integrators, and firmware developers to ensure platform compliance with Arm architectural standards across pre-silicon and silicon phases.
