Abstract
The exemplary embodiments are related to a device, a system, and a method for implementing a hardware mechanism that is configured to validate the performance of scheduling software utilized by a safety-critical system. The hardware device may receive an indication that a first frame of a frame schedule is in use. The hardware device may also monitor a time parameter corresponding to the first frame. The hardware device may also determine whether an indication that a second frame of the frame schedule is in use is received prior to the expiration of the time parameter. When the indication that the second frame of the frame scheduler is in use is not received prior to the expiration of time parameter, the hardware device may send a signal to an operating system of the safety-critical system indicating that an error in executing the frame scheduled has occurred.
