Abstract
A device for high-assurance processing is disclosed. A processing circuit uses an access controller to assure that the processing circuit operates properly. The processing circuit runs software programs and is programmable. The access controller is programmable, but not programmable by the processing circuit. Peripherals or segments of the address space of the processing circuit is regulated. In a particular state, the peripherals that are available are regulated by the access controller. In some embodiments, the transition from state-to-state can also be regulated by the access controller.
