SYSTEM AND METHOD FOR PERFORMING TRANSACTION AGGREGATION IN A NETWORK-ON-CHIP (NOC)

摘要

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.
