摘要： A re-assembly buffer for use in interim storage of aligned data and to reassemble data output onto a wider internal data path, in which the width of the data path is determined to have sufficient bandwidth to account for frequency scaling of received data rate to frequency of the data path and fragmentation of data for alignment onto the data path. The buffer may be is arranged into arrays using single read port, single write port memory devices.

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 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 can be configured in a first mode when supporting an aspect of the HyperTransport Standard and configured in a second mode when supporting the at least one other interface standard. In the alternative, a 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.

摘要： An apparatus includes one or more interface circuits, an interconnect, a memory controller, a memory bridge, a packet DMA circuit, and a switch. The memory controller, the memory bridge, and the packet DMA circuit are coupled to the interconnect. Each interface circuit is coupled to a respective interface to receive packets and/or coherency commands from the interface. The switch is coupled to the interface circuits, the memory bridge, and the packet DMA circuit. The switch is configured to route the coherency commands from the interface circuits to the memory bridge and the packets from the interface circuits to the packet DMA circuit. The memory bridge is configured to initiate corresponding transactions on the interconnect in response to at least some of the coherency commands. The packet DMA circuit is configured to transmit write transactions on the interconnect to the memory controller to store the packets in memory.
