An integrated circuit device (100) comprising a first plurality of components (102-112), a second plurality of buses (114-124, 140, 142) for transmitting transaction requests from said components (102-112) to a resource (138) shared by said components (102-112) and a third plurality of arbiters (132-136) arranged in at least two levels of arbitration. Each transaction request has attached priority value that is used by the arbiters to determine which of the components should be granted access to the resource (138).
