  • Electronic device having a runtime integrity checker
    Patent number: 9542263
    Abstract: An electronic device has a runtime integrity checker for monitoring contents of storage locations in an address range. The runtime integrity checker has a location selector for selecting the storage locations by generating addresses within the address range for locations to be checked, an interface unit coupled to the location selector for receiving the addresses for accessing the locations to be checked via a bus interface, and a processor coupled to the interface unit for retrieving the contents from the locations to be checked. A mask unit is provided for processing a mask for defining the locations to be checked based on bits in the mask. The hardware enables selective monitoring of non contiguous storage locations or data areas.
