    摘要: A method and system to adapt communication links statically and/or dynamically to their individual link conditions on a platform. The communicatively coupled devices have logic to adapt one or more settings of a respective one or more communication links with another device based at least in part on a respective metric of received data patterns from the respective one or more communication links. The communicatively coupled devices in the platform have a back channel to allow feedback or information to be sent from one receiving device to a transmitting device in one embodiment of the invention.

    摘要: Methods and apparatus for embedding a control channel in a high speed serial interconnect having multiple data lanes. Operational aspects of the interconnect are controlled via use of control channel data that is sent over one or more of the data lanes on a periodic basis. A link state cycle is employed that includes a link control period during which control information is transferred over the interconnect and a link control interval between link control periods during which other links states are implemented, such as for transferring data or operating the link in a low power state. The link state cycles at transmitter and receiver ports are synchronized to account for link transmit latencies, and the timing of link state cycles corresponding to a bidirectional exchange of link control information may be configured to support an overlapping implementation or to facilitate a request/response link control protocol.

    摘要: A set of training sequences is generated, each training sequence to include a respective training sequence header, and the training sequence header is to be DC-balanced over the set of training sequences. The set of training sequences can be combined with electric ordered sets to form supersequences for use in such tasks as link adaptation, link state transitions, byte lock, deskew, and other tasks.

    摘要: Methods and apparatus relating to fast deskew when exiting a low-power partial-width high speed link state are described. In one embodiment, an exit flit on active lanes and/or a wake signal/sequence on idle lanes may be transmitted at a first point in time to cause one or more idle lanes of a link to enter an active state. At a second point in time (following or otherwise subsequent to the first point in time), training sequences are transmitted over the one or more idle lanes of the link. And, the one or more idle lanes are deskewed in response to the training sequences and prior to a third point in time (following or otherwise subsequent to the second point in time). Other embodiments are also disclosed and claimed.
