Abstract

A method and apparatus for handling outstanding interconnect transactions between a master device and an interconnect component. For example, a transaction intervention module coupled to an interconnect component and a master device of the interconnect component. The transaction intervention module is arranged to receive an indication of a functional state of the master device. If the master device is indicated as being in a faulty functional state the transaction intervention module is further arranged to determine whether any interconnect transactions initiated by the master device with the interconnect component are outstanding. If it is determined that at least one interconnect transaction initiated by the master device is outstanding, the transaction intervention module is arranged to finalize the at least one outstanding interconnect transaction with the interconnect component.
