Abstract: A broadcast adapter in a network-on-chip (NoC) is used for broadcasting transactions in the form of packets from an initiator to multiple targets and for receiving responses from the targets that are combined and sent to the initiator. The transactions originate from an initiator and are send, using the NoC, to broadcast adapters using a special range of addresses. The broadcast adapters receive the transactions from the initiator. The broadcast adapters duplicate the transactions and send the duplicated transaction to multiple targets. The targets send a response, which is transported back by the NoC to the corresponding initiator.

Abstract: Design of a network-on-chip (NoC) includes searching for a potential deadlock in a topology of the NoC, where the potential deadlock is caused by an external dependency in which input of data into the NoC is dependent on output of data from the NoC. The NoC design further includes modifying the NoC topology to resolve the potential deadlock.

Abstract: An existing network-on-chip (NoC) topology that is derived based on a set of initial requirements is changed using incremental modifications that satisfy a set of updated requirements. Each incremental modification includes minimizing the number of changes to existing components in the existing NoC topology. Minimizing the changes includes preserving names of the existing components in the existing NoC topology and removing existing components or connections as well as adding in new component and new connections.

Abstract: Systems and methods are disclosed for synthesis of a network, such as a network-on-chip (NoC), to generate a network description. The system generates a NoC description from a set of physical constraints and performance constraints as well as a set of inputs to a sequencer. The system produces the NoC with all its elements. The resulting network description output includes placement of elements on a floorplan of a chip that represents the network, such as the NoC.

Abstract: System and methods are disclosed for aggregating identical requests sent to a target from multiple initiators through a network-on-chip (NoC). The requests are marked for aggregation. The NoC uses request aggregators (RA) as an aggregation point to aggregate the identical requests that are marked for aggregation. At the aggregation point, the identical requests are reduced to a single request. The single request is sent to the target. The process is repeated in a cascaded fashion through the NoC, possibly involving multiple request aggregators. When a response transaction is received back from the target, which is at the aggregation point closest to the target, the response transaction is duplicated and sent to every original requester, either directly or through other request aggregators, which further duplicate the already duplicated response transaction.
