Abstract: A first storage location at a memory management unit stores physical address information mapping logical physical addresses to actual physical addresses. A second storage location stores an allowed address range of actual physical addresses. A memory management unit determines whether a write access to the first storage location is allowable. The access is to store memory mapping information relating to a first actual physical address. The memory management unit prevents the write access if the first actual physical address is not in the allowed address range, and does not prevent the write access if the first actual physical address is in the allowed address range. The memory management unit prevents a write access to the second storage location by a process that is not running in a hypervisor mode.

As such, measurements are compared with the corresponding expected value for a particular variable. If the difference between a measurement and its corresponding expected value is found to be unacceptable, the validation computer will generate a corresponding alert. Application examples include 1) validating wired sensors used in safety shutdown systems for industrial facilities and 2) validating wired sensors used to monitor storage tanks.
