Abstract
The present application discloses a processing unit and an access detection method thereof. The processing unit includes an execution circuit. The execution circuit connects to a memory and is configured to: execute an access request, wherein the access request is for accessing at least one part of a first physical memory section corresponding to a first access base address; determine whether a first tag of the access request is equal to a second tag corresponding to the first memory base address and whether the at least one part of the first physical memory section matches a first legal access section corresponding to the first memory base address; and determine whether to send an alert message according to the determination result.
