A system includes a processor having first and second processing units and a memory coupled to the processor. The memory includes processor executable code to implement an application to execute a first process to provide first application output information and to execute a second process to provide second application output information, a selector to provide a first indication that the first process is a critical process and a second indication that the second process is a non-critical process, and an application program interface (API) to run on the first processing unit. The API directs the processor to run the application on the second processing unit, executes the first process to provide first API output information in response to the first indication; determines if the first application output information matches the first API output information, and determines to not execute the second process in response to the second indication.
