Abstract: A system includes a plurality of systems-on-a-chip (SoCs), connected by a network. The plurality of SoCs and the network are configured to operate as a single logical computing system. The plurality of SoCs may be configured to exchange local power information indicative of network activity occurring on their respective portions of the network. A given one of the plurality of SoCs may be configured to determine that a local condition for placing the respective portion of the network corresponding to the given SoC into a reduced power mode has been satisfied. The given SoC may be further configured to place the respective portion of the network into the reduced power mode in response to determining that a global condition for the reduced power mode is satisfied. The global condition may be assessed based upon current local power information for remaining ones of the plurality of SoCs.

Abstract: An apparatus includes an interface circuit and an encoder circuit. The interface circuit is configured to send a data packet via a plurality of segments, and to send an idle value via the plurality of segments when no data packet is available. The idle value is configured to cause a segment in a receiving apparatus to idle. The encoder circuit is configured to receive a particular data packet, and, if a portion of the particular data packet has a same value as the idle value for a subset of the plurality of segments, to replace at least a portion of the data packet with a mask value to generate a modified data packet. The mask value indicates how to recreate the particular data packet. The encoder circuit is further configured to send the modified data packet to the receiving apparatus via the plurality of segments of the interface circuit.
