DATA PROCESSOR HAVING MODULE ACCESS CONTROL

摘要

A data processor (12) cooperates with an access controller (14) to control access to a module stored in a storage device (20). In response to receiving an instruction which requests access to the module and specifies an address within the storage device (20) containing an access request, the data processor (12) retrieves the access request and provides the access request to the access controller (14). The data processor (12) will then initiate the requested access. However, the access will be faulted if the access controller (14) decides to deny the access request.
