Computer system and method for comparing output signals

摘要

A computer system includes at least two COTS processor cores and an evaluating device connected to the at least two COTS processor cores for evaluating output signals output by means of the at least two COTS processor cores. The evaluating device includes a comparator for pair-wise comparison of the respective generated output signals with each other. The comparator also outputs a comparison signal corresponding to the respective comparison of the output signals.

1. A computer system, comprising:
at least three commercial off-the-shelf (COTS) processor cores; and an evaluation device, which is connected to the at least three COTS processor cores, the evaluation device is configured to evaluate output signals that are output from the at least three COTS processor cores, wherein the evaluation device includes a comparator configured to compare a relocatable group of the output signals that are output with one another in pairs, wherein the comparator of the evaluation device is also configured to output a comparison signal that corresponds to the respective comparison of the relocatable group of the output signals, and wherein at least one of the COTS processor cores is different than the other COTS processor cores, a selection device, connected to the comparator of the evaluation device, configured to select an output signal for further processing based on the comparison signal, the at least three COTS processor cores each comprise a corresponding comparator to compare non-relocatable output signals of the output signals with one another, and the computer system further comprises a switching device that is connected between the COTS processor cores and the comparator of the evaluation device, wherein the switching device is configured to transmit the relocatable group of the output signals to the comparator of the evaluation device on the basis of a utilization state of the comparator of the evaluation device.
