    摘要: A dual mode digital interface supports the HyperTransport Standard and at least one other interface standard. The dual mode digital interface includes a physical interface, a plurality of data line amplifiers, a clock line amplifier, a plurality of data line deskew/sampling blocks, a data group deskew module, and an enablement control module. The plurality of data line deskew/sampling blocks deskew and sample incoming data on respective data lines based upon a clock signal to produce deskewed data. The data group deskew module receives deskewed data from each of the plurality of data line deskew/sampling blocks and removes inter data line skew from the deskewed data to produce received data. The plurality of data line deskew/sampling blocks and the data group deskew module may be set based upon a training sequence received from a link partner. The training sequence may received during startup or reset, immediately after startup or reset completes, or may be received periodically during training intervals.

    摘要: A method for receiving data from a plurality of virtual channels begins by storing a stream of data as a plurality of data segments, wherein the stream of data includes multiplexed data fragments from at least one of the plurality of virtual channels, and wherein a data segment of the plurality of data segments corresponds to one of the multiplexed data fragments. The method continues by decoding at least one of the plurality of data segments in accordance with one of a plurality of data transmission protocols to produce at least one decoded data segment. The method continues by storing the at least one decoded data segment, in a generic format, to reassemble at least a portion of a packet provided by the at least one of the plurality of virtual channels. The method continues by routing the at least one decoded data segment as at least part of the reassembled packet to one of a plurality of destinations in accordance with the at least one of the plurality of virtual channels.
