摘要： Smart routing between peers in a point-to-point link based system begins when a device of a plurality of devices in a point-to-point link interconnected system receives a packet from an upstream link or a downstream link. The processing continues when the device interprets the packet to determine a destination of the packet. If the device is the destination of the packet, the device accepts the packet. If, however, the device is not the destination of the packet, the device forwards the packet on another upstream link or another downstream link without alteration of at least one of: source information of the packet and destination information of the packet.

摘要： Techniques are disclosed relating to integrated circuits that implement a virtual memory. In one embodiment, an integrated circuit is disclosed that includes a translation lookaside buffer configured to store non-prefetched translations and a translation table configured to store prefetched translations. In such an embodiment, the translation lookaside buffer and the translation table share table walk circuitry. In some embodiments, the table walk circuitry is configured to store a translation in the translation table in response to a prefetch request and without updating the translation lookaside buffer. In some embodiments, the translation lookaside buffer, the translation table, and table walk circuitry are included within a memory management unit configured to service memory requests received from a plurality of client circuits via a plurality of direct memory access (DMA) channels.

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.
