Patent ID: 7966082

Claim:
A method for operating a calculating unit that executes a software program, comprising: inputting a plurality of input signals, to the software program; processing the plurality of input signals, by the software program; generating a plurality of output signals by the software program; feeding-back at least one of the plurality of output signals of the software program to the input of the software program; marking a portion of each input signal that is inputted and processed by the software program, wherein the marking is correlated with the quality of the corresponding input signals to indicate a dominant or non-dominant marking, wherein the dominant marking is passed on in further processing of the corresponding signals to at least one of the output signals generated in the further processing; correlating an attribute of the further processed signals with a current inheritance frequency of the dominant marking; correlating an attribute of each of the plurality of input signals with the inheritance frequency of one of the plurality of input signals having a smallest inheritance frequency; comparing a current value of the attribute with a predetermined inheritance frequency limit value that identifies a frequency that the marking may be inputted and processed by the software program; and re-setting the dominant marking to a non-dominant marking if the inheritance frequency limit value is exceeded.
