Abstract
An apparatus and method are provided for handling ordered transactions. The apparatus has a plurality of completer elements to process transactions, a requester element to issue a sequence of ordered transactions, and an interconnect providing, for each completer element, a communication channel between that completer element and the requester element for transfer of signals between that completer element and the requester element in either direction. A given completer element that is processing a given transaction in the sequence is arranged to issue a response signal to the requester element over its associated communication channel that comprises an ordered channel indication to identify whether the associated communication channel has an ordered channel property. The ordered channel property guarantees that processing of transactions issued by the requester element over the associated communication channel in a given order will be completed by the given completer element in the same given order. The requester element is then responsive to the ordered channel indication to control timing of issuance from the requester element of at least one signal relating to one or more transa…
