摘要： A high speed multi-lane serial interface and method for constructing frames for such an interface are provided. Frames are constructed for transmission on a multi-lane serial interface. For each of a plurality of transmit channels, packets are fragmented into fragments. Meta-frames are generated having a size defined by a constant meta-frame length×number of lanes, each frame having a meta-frame separator and a payload. Per-transmit channel flow control information is received. Each payload has a plurality of bursts, each burst comprising a burst control word and an associated data burst, the burst control word identifying one of said transmit channels to be transmitted on the associated data burst, each data burst comprising one of the fragments for the transmit channel identified in the associated burst control word. The channels to transmit in a given meta-frame are selected as a function of the received flow control information.

摘要： An apparatus consisting of a digital communication channel comprised of a multiplicity of lanes where data is striped across the lanes in a predefined sequence. Each lane has the ability to be powered down or powered up in response to the amount of data being held in a transmit buffer at one end of the communication channel. The method consists of monitoring the amount of data being held in the transmit buffer; making the decision of how many lanes are required based on the amount of data; sending signals to cause the required number of lanes to be powered down or powered up; and performing the required power down or power up action at the particular transmitter and receiver. The fill level of the transmit buffer is continually monitored and the required number of active lanes and the striping sequence is calculated and updated as required as a function of the fill level, where a larger amount of data waiting to be transmitted will result in a greater number of lanes being powered up and a smaller amount of data waiting to be transmitted will result in a lesser number of lanes being powered up.
