Abstract
A system on chip includes an interconnect circuit including at least p input interfaces and at least k output interfaces, p source devices respectively coupled to the p input interfaces and k access ports respectively coupled to the k output interfaces and belonging to a target that includes one or more target devices. Each source device is configured to deliver transactions to the target via one of the access ports. An associated memory of each access port is configured to temporarily store the transactions received by the access port. The target is configured to deliver, for each access port, a fill signal representative of a current fill level of its associated memory. A control circuit is configured to receive the fill signals from the access ports and select the access ports eligible to receive a transaction depending on the current fill levels.
