    • A method and apparatus for intelligent power management for low power link states. Some embodiments include methods, apparatuses, and systems for a device coupled to a controller via a link; a link power management engine to alter a power state of the link based on a transaction and some knowledge of future transactions between the device and the controller; and a memory or logic to store the link power management engine. In some embodiments, the memory stores information about at least one of the following: the power state of the link, the device buffering, the controller or device state or a history of transactions. In some embodiments, the device is a peripheral of a computer system. In some embodiments, the method may include transitioning the device to various link states. Other embodiments are described.
    • 一种用于低功率链路状态智能电源管理的方法和装置。 一些实施例包括用于经由链路耦合到控制器的设备的方法,设备和系统; 链路功率管理引擎,用于基于事务改变链路的功率状态以及对设备和控制器之间的未来事务的一些知识; 以及用于存储链路电源管理引擎的存储器或逻辑。 在一些实施例中,存储器存储关于以下至少一个的信息:链路的功率状态,设备缓冲,控制器或设备状态或事务历史。 在一些实施例中,设备是计算机系统的外设。 在一些实施例中,该方法可以包括将设备转换到各种链路状态。 描述其他实施例。
