In September 2004, revision 3.0 was released, bringing to the ACPI specification support for SATA interfaces, PCI Express bus, multiprocessor support for more than 256 processors, ambient light sensors and user-presence devices, as well as extending the thermal model beyond the previous processor-centric support. It was not until August 2000 that ACPI received 64-bit address support as well as support for multiprocessor workstations and servers with revision 2.0. The first revision of the ACPI specification was released in December 1996, supporting 16, 24 and 32-bit addressing spaces.

The ACPICA code is used by Linux, Haiku, ArcaOS and FreeBSD, which supplement it with their operating-system specific code. The ACPI Component Architecture ( ACPICA), mainly written by Intel's engineers, provides an open-source platform-independent reference implementation of the operating system–related ACPI code. In 2014, Mark Shuttleworth, founder of the Ubuntu Linux distribution, compared ACPI with Trojan horses.

In 2001, other senior Linux software developers like Alan Cox expressed concerns about the requirements that bytecode from an external source must be run by the kernel with full privileges, as well as the overall complexity of the ACPI specification. In November 2003, Linus Torvalds-author of the Linux kernel-described ACPI as "a complete design disaster in every way". Overall design decision was not without criticism. At the BIOS development time, AML bytecode is compiled from the ASL (ACPI Source Language) code.
A reference AML interpreter implementation is provided by the ACPI Component Architecture (ACPICA).
To make use of the ACPI tables, the operating system must have an interpreter for the AML bytecode. Many of the firmware ACPI functionality is provided in bytecode of ACPI Machine Language (AML), a Turing-complete, domain-specific low-level language, stored in the ACPI tables. The ACPI BIOS generates ACPI tables and loads ACPI tables into main memory. The firmware-level ACPI has three main components: the ACPI tables, the ACPI BIOS, and the ACPI registers.
