工程师 - ACPI介绍_1

通过高级电源管理 (APM)，电源管理由 BIOS 控制，与操作系统无关。当超出 BIOS 设置时，BIOS 会关闭屏幕或硬盘。这就产生了一种不完善的电源管理策略，因为它需要为每个平台重新实施策略。 即插即用 BIOS（PNPBIOS）规范也不可靠。

With advanced power management (APM), power management is controlled by the BIOS independently of the operating system. When BIOS settings are exceeded, the BIOS turns off the screen or shuts down the hard drive. This creates an imperfect power management policy because it requires reimplementing the policy for each platform.  Plug and play BIOS (PNPBIOS) specification is also unreliable.

有了 ACPI，电源管理从 BIOS 转移到操作系统。

• 应用程序可以告诉操作系统显示器正在使用中，并相应改变其电源策略。

• 操作系统没有 BIOS 的大小限制。

• ACPI 系统固件通过将数据整理成表格放入主内存来描述系统特性。

With ACPI, power management moves from the BIOS to the operating system.

* An application can tell the operating system that the display is in use, and change its power policy accordingly.

* The operating system does not have the size limitation of the BIOS.

* The ACPI system firmware describes the system's characteristics by placing data, organized into tables, into the main memory.

ACPI（高级配置和电源接口）是计算机硬件配置和电源管理的开放标准。目前，从笔记本电脑、台式机到服务器等一系列设备都广泛采用了这一标准。ACPI 的目标是让操作系统控制电源管理，而不是依赖 BIOS 或硬件专用驱动程序。这将提高能源效率，实现更有效的电源管理，并改善系统性能。

ACPI (Advanced Configuration and Power Interface) is an open standard for hardware configuration and power management in computers. It is now widely adopted across a range of devices, from laptops and desktops to servers. The goal of ACPI is to allow the operating system to take control of power management, rather than relying on the BIOS or hardware-specific drivers. This leads to better energy efficiency, more effective power management, and improved system performance.

高级配置和电源接口（ACPI）是由英特尔、微软和东芝等公司开发的一种开放式行业规范。它为操作系统建立了一种管理计算机硬件功耗和配置的标准方法。ACPI 允许操作系统控制提供给各种内部组件、外围设备和整个系统的电量，这有助于节约能源和延长便携式设备的电池寿命。

The Advanced Configuration and Power Interface (ACPI) is an open industry specification developed by companies such as Intel, Microsoft, and Toshiba. And it establishes a standard way for operating systems to manage power consumption and configuration of computer hardware. ACPI allows operating systems to control the amount of power supplied to various internal components, peripheral devices, and the entire system, which helps in conserving energy and extending battery life in portable devices.

ACPI 是高级配置和电源接口的简称，它定义了一个灵活而抽象的硬件接口。它提供了一种将电源管理功能集成到整个 PC 系统（包括硬件、操作系统和应用软件）的标准方法。ACPI 允许计算机打开 CD-ROM、网卡、硬盘驱动器和打印机等外围设备以及其他 ACPI 兼容产品。有了这项技术，外设也能激活电脑。例如，将一盘磁带插入录像机（VCR），就可以打开电脑，从而激活电视和高保真音响系统。

Short for Advanced Configuration and Power Interface, ACPI defines a flexible and abstract hardware interface. It provides a standard way to integrate power management features throughout a PC system, including the hardware, operating system and application software. ACPI allows a computer to turn on peripherals such as CD-ROMs, network cards, hard drives, and printers, and other ACPI compatible products. With this technolog
