Abstract
An electronic system comprises a control unit for ordering the storage of an index value for indexed registers, in an additional index register linked to a defined initiator module, in response to a request to write the index value in an index register linked to the indexed registers, initiated by the initiator module. In response to any request to access an indexed register initiated by a defined initiator module, the control unit copies the index value from the additional index register linked to this initiator module to the index register linked to this indexed register, prior to execution of the access request. This enables management of access to indexed registers associated with an arbitration mechanism provided for managing conflicting access requests initiated by different functional modules in a system on a chip.
