    摘要: Methods and apparatus relating to enhanced interconnect link width modulation for power savings are described. In one embodiment, the width of a link is modified from a first width to a second width in response to a power management flit, while non-idle flits continue to be transmitted over the link after transmission of the power management flit. Other embodiments are also disclosed and claimed.

    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: Methods and apparatus relating to repurposing a data lane as a clock lane by migrating to reduced speed link operation are described. In one embodiment, speed of a link is reduced upon detection of failure on a clock lane of the link and one of a plurality of data lanes of a link is repurposed as a replacement clock lane. Other embodiments are also disclosed and claimed.

    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.
