A system and method for integrity monitoring on a heterogeneous system-on-a-chip (SoC) processing environment provides sets of dynamic input data to integrity applications running on one or more application cores (e.g., where safety critical applications are hosted) which generate an integrity output according to function/instruction sets. The dynamic input data is also provided to an integrity monitor running on a dissimilar integrity core (e.g., different architecture and/or other core type than the application cores) which receives the integrity output from the application cores and generates its own integrity result based on the same function sets and the same dynamic input data. The integrity monitor compares the local integrity result to the integrity outputs received from the application cores. If the integrity outputs deviate from the integrity result, the integrity core initiates a fault response, which may include resetting the deviant application core, all application cores, or the full SoC environment.
