摘要： An apparatus includes a first interface circuit, a second interface circuit, a memory controller for configured to interface to a memory, and a packet DMA circuit. The first interface circuit is configured to couple to a first interface for receiving and transmitting packet data. Similarly, the second interface circuit is configured to couple to a second interface for receiving and transmitting packet data. The packet DMA circuit is coupled to receive a first packet from the first interface circuit and a second packet from the second interface circuit. The packet DMA circuit is configured to transmit the first packet and the second packet in write commands to the memory controller to be written to the memory. In some embodiments, a switch is coupled to the first interface circuit, the second interface circuit, and the packet DMA circuit.

摘要： An integrated circuit includes receive circuits for receiving packets, transmit circuits for transmitting packets, a packet DMA circuit for communicating packets to and from a memory controller, and a switch for selectively coupling the receive circuits to transmit circuits. The integrated circuit may flexibly merge and split the packet streams to provide for various packet processing/packet routing functions to be applied to different packets within the packet streams. An apparatus may include two or more of the integrated circuits, which may communicate packets between respective receive and transmit circuits.

摘要： An apparatus may include a first system and a second system. The first system includes a first plurality of interface circuits, and each of the first plurality of interface circuits is configured to couple to a separate interface. The second system includes a second plurality of interface circuits, and each of the second plurality of interface circuits is configured to couple to a separate interface. A first interface circuit of the first plurality of interface circuits and a second interface circuit of the second plurality of interface circuits are coupled to a first interface. Both the first interface circuit and the second interface circuit are configured to communicate packets, coherency commands, and noncoherent commands on the first interface.

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.
