Abstract
Apparatus for processing data is provided comprising processing circuitry and monitoring circuitry for monitoring write transactions and performing transaction authorizations of certain transactions in dependence upon associated memory addresses. The processing circuitry is configured to enable execution of a write instruction corresponding to a write transaction to be monitored to continue to completion while the monitoring circuitry is performing monitoring of the write transactions and the monitoring circuitry is arranged to cause storage of write transaction data in an intermediate storage element for those transactions for which an authorization is required. Storage of write transaction data in an intermediate storage element enables the write transaction to be reissued in dependence upon the result of the transaction authorization although the corresponding write instruction has already completed.
