Abstract
In at least some embodiments, a system comprises a hardware unit and a plurality of software agents that couple to and utilize at least one function of the hardware unit. The system further comprises a consensus module coupled to the hardware unit and the software agents. The consensus module is configured to detect an event that changes a state of the hardware unit, notify the software agents of the event before the state changes and selectively permit the state to change based on responses from the software agents.
