Abstract: Method for monitoring the execution of an application software implementing a safety function, comprising implementing a software-based lock step on a dual asymmetrical processing units structure, the processing units structure including a first processing unit and a second processing unit having, due to the asymmetry, a different hardware structure and/or lower computations capability with respect to the first processing unit. A first runtime software is executed on the first processor while a second runtime software being a potentially modified version of the first runtime software and having the same behavior as that of the first runtime software, is executed on the second processor.
