Estimating the term…
An access control function for an integrated system is provided which determines data access based on the master id of a requesting master within the system and the address of the data. The access control function can be inserted, for example, into the data transfer path between bus control logic and one or more slaves. In addition to determining whether to grant access to the data, the access control function can further qualify the access by selectively implementing encryption and decryption of data, again dependent on the data authorization level for the particular functional master initiating the request for data.
A data access method for an integrated system having multiple functional masters, the-multiple functional masters having multiple master ids, the method comprising:
A data access system for an integrated system having multiple functional masters, the multiple functional masters having multiple master ids, the data access system comprising:
At least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform a data access method for an integrated system having multiple functional masters, the multiple functional masters having multiple master ids, the method comprising:
