A processing system, such as for an automobile, includes multiple processor cores, including an application core and a safety core, and a fault detection circuit in communication with the processor cores. The fault detection circuit includes a progress register for storing progress data of an application executed on the application core. The safety core, which executes a fault detection program, reads the progress data from the progress register, and generates an output based on the progress data and an expected behavior of the application. The safety core writes the output to a status register of the fault detection circuit. The fault detection circuit includes a controller that reads the status register and generates a fault signal when the output indicates there is a fault in the execution of the application. In response, the application core either recovers from the fault or runs in a safe mode.
