A multi-function system comprising a plurality of peripherals having different levels of susceptibility to environmental events, at least one event detector configured to detect environmental events, a controller coupled to receive an event detected signal from the at least one event detector, a communication interface communicatively coupling the controller and each peripheral that includes an internal central processing unit, and a dedicated control interface communicatively coupling the controller and the plurality of peripherals. The controller is configured to control circumvention procedures of each peripheral via the dedicated control interface based on the detected event and the level of susceptibility of the peripheral.

Method for implementing a control channel in a system of circumvention and recovery

A method of implementing a circumvention and recovery system comprising conveying peripheral identifiers to a controller, and determining a level of susceptibility of a peripheral to select events based on the peripheral identifier. The method further includes controlling each peripheral based on the level of susceptibility of the peripheral during detection of a select event.

Method of peripheral type identification in a system of circumvention and recovery

A system comprises at least one non-hardened processor configured to run a plurality of mission related processes; at least one threat detector configured to detect one or more conditions which indicate the onset of a threat to the operation of the at least one non-hardened processor; and at least one hardened processor configured to elevate at least one health monitoring process of the at least one non-hardened processor from a background process to a foreground process when the at least one threat detector detects a condition indicating the onset of a threat, wherein the at least one hardened processor manages the operation of the at least one non-hardened processor based on the results of the at least one health monitoring process.
