Abstract

In a system on chip responder units comprise one or more responder elements and is associated with one or more protection units. A request analysis unit is arranged to receive from a requesting requestor unit a request for access to one or more target responder elements among responder elements within a target responder unit among the responder units. The request analysis unit determines relevant protection data based on the request and an authorization list, which comprises one or more entries For each entry of the authorization list: taking access requirements specified by the respective entry into account if one or more of the target responder elements are part of the group of responder elements specified by the respective entry. The request analysis unit provides the relevant protection data to one or more target protection unit(s) associated with the responder unit(s), and located in a hierarchical path between the requesting requestor unit requestor unit and the target responder unit. The target protection unit(s) are arranged to perform a protective action for the target responder elements based on relevant protection data.
