摘要

Error detection devices, systems and methods are provided that implement identical processors. A first processor is configured to receive a first measurement, execute a first firmware based on the first measurement, and output a first result of the executed first firmware. A second processor, which is identical to the first processor, is configured to receive a second measurement, to execute a second firmware based on the second measurement, and to output a second result of the executed second firmware. The first firmware and the second firmware provide a nominal function in a variety of ways for computing the first result and / or the second result such that the first result and the second result are expected to be within a predetermined range. Thus, an error can be detected by comparing the first and second results.
