Abstract
A system and method for processing data for use with a microcontroller having a processing unit provides for sending an input data address to a memory as part of a read request for input data stored in the memory, receiving the input data from the memory, generating a plurality of trace signals, generating a first plurality of signatures based upon the plurality of trace signals, receiving a second plurality of corresponding signatures from a second microcontroller, comparing each signature of the first plurality of signatures to each corresponding signature of the second plurality of corresponding signatures, generating a first error signal if the comparison produces at least one mismatch, and utilizing the first error signal to generate one or more disable signals for disabling operation of one or more devices under control of the microcontroller.
