摘要：A data processing apparatus supports operation in both a secure domain and aless secure domain. The secure domain has access to data that is not accessible whenoperating the less secure domain. Prediction circuitry generates a domain prediction
indicating whether a given processing action (such as a memory access) is to be
performed in association with the secure domain or with the less secure domain. In thisway, an appropriate set of memory permission data for controlling access by differentprivilege levels in the domains may be selected and applied by an appropriate memoryprotection unit. If the domain prediction is incorrect, then the processing is stalled andthe given processing action retried.
