ACPICA

Introduction

The ACPI Component Architecture (ACPICA) project provides an OS-independent reference implementation of the ACPI specification. It can be easily adapted to any host OS. The ACPICA code is meant to be directly integrated into the host OS, as a kernel-resident subsystem. Hosting the ACPICA requires no changes to the core ACPICA code. However, it does require a small OS-specific interface layer, which must be written specifically for each host OS.

Components ACPICA components include:

• an AML interpreter and debugger
• ACPI namespace support
• ACPI hardware and event support
• a full ASL compiler and disassembler
