Systems and methods are disclosed for broadcasting transactions, inside a network-on-chip (NoC), from a master to multiple slaves and for receiving responses. The transactions originate from a master and are send, using the NoC, to broadcast adapters using a special range of addresses. The broadcast adapters receive the transactions from the master. The broadcast adapters duplicate the transactions and send the duplicated transaction to multiple slaves. The slaves send a response, which is transported back by the NoC to the corresponding master.
