CPC classification number: G06F13/4273
Abstract: A method and apparatus for advancing initialization messages when initializing an interface is presented. In one embodiment, one of a sequence of training sequence messages are sent in serial mode across the data lanes of a generally-parallel interface between two agents. When one agent correctly receives a fixed number of messages, it may begin sending its messages with an acknowledgement. Thereafter, when that agent correctly receives a fixed number of messages including an acknowledgement, that agent may advance to sending the next training sequence messages in the sequence.
Abstract translation: 提出了一种在初始化界面时推进初始化消息的方法和装置。 在一个实施例中，训练序列消息序列中的一个在两个代理之间的通常并行接口的数据通道上以串行模式发送。 当一个代理正确接收到固定数量的消息时，它可以开始发送其确认消息。 此后，当该代理正确地接收到包括确认的固定数量的消息时，该代理可以推进以顺序发送下一个训练序列消息。

Abstract: Disclosed are embodiments of a method, apparatus and system for a low power state for a point-to-point link. During the low power state, the signal on both conductors of a differential transmit pair are driven to electrical idle. Analog activity detectors are enabled during the low power state and are disabled during normal power state. Exit from the low power state does not require a physical layer re-initialization sequence. Other embodiments are also described and claimed.
Abstract translation: 公开了用于点对点链路的低功率状态的方法，装置和系统的实施例。 在低功率状态期间，差分发送对的两个导体上的信号被驱动到电气空闲。 模拟活动检测器在低功率状态期间被使能，并且在正常功率状态期间被禁用。 退出低功耗状态不需要物理层重新初始化的顺序。 还描述和要求保护其他实施例。

Abstract: Redundant acknowledgment between agents performing a loopback test over bidirectional communications bus is described. In one example the acknowledgment is performed by initiating loopback communications from a first agent to a second agent, sending a packet including a redundant acknowledgment sequence from the first agent to the second agent, receiving the packet including the redundant acknowledgement sequence looped back from the second agent at the first agent, sending a test sequence from the first agent to the second agent, and receiving the test sequence looped back from the first agent.
