1. A method for operating a control unit, the control unit including: a plurality of single-chip systems each embodied as a respective system-on-chip (SoC) set up to obtain sensor data that is identical for all of the SoCs, wherein each of the SoCs is assigned a different respective one of a plurality of predefined functions that the respective SoC, and not others of the SoCs, is to perform at a first performance level with respect to at least one predefined performance criterion and using a respective portion of the identical sensor data, when the respective SoC is in a faultless state, the method comprising:
sensing that one of the SoCs, to which a first of the plurality of predefined functions had been assigned for performance at the first level, is in a failure state;
responsive to the sensing of the one of the SoCs being in the failure state, performing a reassignment that includes:
determining which one or more of others of the plurality of SoCs are to replace the SoC that has been sensed as being in the failure state for performance of the first predefined function that had been assigned to the SoC that is in the failure state;
executing a degradation mechanism to identify a second performance level at which to perform the first predefined function, the second performance level being degraded with respect to the at least one predefined performance criterion compared to the first performance level; and
assigning to the determined one or more of the others of the plurality of SoCs a degraded performance of the first predefined function at the second performance level and using the sensor data; and
based on the reassignment, implementing, by the determined one or more of the others of the plurality of SoCs, the degraded performance of the first predefined function at the second performance level.
