    Abstract: A virtual wire system includes a source device, a target device, and a mesh interface connecting the source device and the target device. One or more mesh messages are transmitted over the mesh interface from the source device to the target device, and the one or more mesh messages indicate a change in a value of a signal level at the source device. The source device may include a plurality of virtual wire sources, a virtual wire encoder, and a virtual wire arbiter operatively coupled to the plurality of virtual wire sources and the virtual wire encoder. The virtual wire arbiter is configured to determine whether information from a virtual wire source should be transmitted to the virtual wire encoder. The virtual wire encoder is configured to receive information from the virtual wire arbiter, combine the information into a single virtual wire message, and transmit the single virtual wire message to a first mesh interface component in the source device.

    Abstract: An integrated circuit includes a set of functional units having at least a first functional unit and a second functional unit. The first functional unit includes first processing circuitry and a first circuit coupled to the first processing circuitry to receive a message from the second functional unit of the set of functional units. The first circuit is further to delay the message for the first processing circuitry for a predetermined duration, where the predetermined duration is based in part on a first value representing a first distance between the first functional unit and the second functional unit and a second value representing a second distance between the second functional unit and a functional unit of the set of functional units that is farthest away from the second functional unit.

    Abstract: A system including an array of functional units connected via a two-dimensional mesh network is described. A first functional unit in the array of function units includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including generating a node identifier identifying a second functional unit in the array of functional units, and transmitting, over the two-dimensional mesh network, the node identifier identifying the second functional unit in the array of functional units. The node identifier may include a mesh interface component and a port identifier, and one or more information elements selected from the group consisting of a payload, a target node identifier, a target type identifier, an information type identifier, a linear identifier, and a protocol identifier.

    Abstract: A computing system comprises one or more cores. Each core comprises a processor. In some implementations, each processor is coupled to a communication network among the cores. In some implementations, a switch in each core includes switching circuitry to forward data received over data paths from other cores to the processor and to switches of other cores, and to forward data received from the processor to switches of other cores. Also disclosed is a cache coherency protocol that includes both an “Owned” state and a Forward state together with protocol mechanism for handling various memory requests.
