Abstract
A vehicle includes a high assurance processing system including a plurality of data processors coupled in parallel, a bridge coupled to the input/output processor, and an input/output processor coupled to the bridge for coupling to a sensor and an effector. Sensor data passes to the bridge through the input/output processor for processing by the parallel data processors, which generate redundant effector data for comparison by the bridge to detect errors. If data matches are found, data is transmitted to the effector.

A vehicle, comprising:
- a high assurance bridge;
- a plurality of data processors coupled in parallel to the high assurance bridge;
- and
- an input/output processor coupled to the bridge, the input/output processor adapted to be coupled to a sensor and an effector;
