    摘要： A first flit is generated according to a first flit format, where a first number of error detection codes are to be provided for an amount of data to be sent in the first flit, and the first flit is to be sent on a link by the transmitter while the link operates with a first link width. The link transitions from a first link width to a second link width, where the second link width is narrower than the first link width. A second flit is generated according to a second flit format based on the transition to the second link width, where the second flit is to be sent while the link operates at the second link width, and the second flit format defines that a second, higher number of error detection codes are to be provided for the same amount of data.

    摘要： Methods, apparatus, and systems, for transporting data units comprising multiple pieces of transaction data over high-speed interconnects. A flow control unit, called a KTI (Keizer Technology Interface) Flit, is implemented in a coherent multi-layer protocol supporting coherent memory transactions. The KTI Flit has a basic format that supports use of configurable fields to implement KTI Flits with specific formats that may be used for corresponding transactions. In one aspect, the KTI Flit may be formatted as multiple slots used to support transfer of multiple respective pieces of transaction data in a single Flit. The KTI Flit can also be configured to support various types of transactions and multiple KTI Flits may be combined into packets to support transfer of data such as cache line transfers.

    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.

    摘要： Method, apparatus, and systems employing dictionary-based high-bandwidth lossless compression. A pair of dictionaries having entries that are synchronized and encoded to support compression and decompression operations are implemented via logic at a compressor and decompressor. The compressor/decompressor logic operatives in a cooperative manner, including implementing the same dictionary update schemes, resulting in the data in the respective dictionaries being synchronized. The dictionaries are also configured with replaceable entries, and replacement policies are implemented based on matching bytes of data within sets of data being transferred over the link. Various schemes are disclosed for entry replacement, as well as a delayed dictionary update technique. The techniques support line-speed compression and decompression using parallel operations resulting in substantially no latency overhead.
