Abstract: Systems and methods for reducing power consumption of systems using serialized data transmission. In a multi-node system, the reiterative steps for the setup of the lanes within links between the nodes produces both a time invariant set of parameters associated with the channel properties of the lanes and a time variant set of parameters associated with receiver clock alignment. The time invariant set is stored in persistent storage. Links may be turned on and turned off. When a link is turned on again, the stored time invariant set may be used as initial values to reconfigure both the time invariant and the time variant sets, thereby greatly reducing the delay to begin using the link again. The reduced delay may significantly speed up the wakening process for the links, thereby encouraging the use of low-power techniques that include tuning off lanes.

Abstract translation: 使用串行数据传输降低系统功耗的系统和方法。 在多节点系统中，用于在节点之间的链路内建立通道的重复步骤产生与通道的通道属性相关联的时间不变量参数和与接收器时钟对准相关联的参数的时变集合。 时间不变集存储在持久存储器中。 链接可能会打开并关闭。 当再次打开链接时，可以将所存储的时间不变集合用作初始值以重新配置时间不变集合和时间变量集合，从而大大减少开始再次使用链接的延迟。 减少的延迟可能会显着加速链路的唤醒过程，从而鼓励使用包括调整车道的低功率技术。
